482. Purity Can Be Toxic
Drinking absolutely pure water can kill us. All the water we normally drink, from taps, bottles, or the garden hose, contains impurities that affect a property of water called tonicity. This is a solution's ability to draw or repel water from adjacent solutions when separated by a membrane. Hypertonic solutions gain water, while hypotonic solutions lose water. Absolutely pure water, with no impurities at all, is the most hypotonic solution. So, if we drink enough of it, our cells will start absorbing water. This disturbs the balance of electrolytes in our body. This is most seriously a problem in the brain, where water poisoning can lead to brain damage, coma and even death. If truth is like water, 100% truth will kill us. Seeking purity in all our communication is actually toxic to our relationships. Expecting laser clarity of the heart's intention to be communicated all the time is not only infeasible but also only worsens a relationship. If we spoke 100% of our intentions and what is in our hearts to the people around us every day, they would probably want to be alone for the rest of their lives. Why? Because we cannot handle 100% truth about ourselves and what people think. Though some people claim they want truth and nothing but the truth, most of us want some cushion to minimize the impact of hard truths in communication. So we need to accept that we can never be 100% clear and pure in all our communication. It is said that there are 4 different levels of communication that happen in every conversation: What I think I said What I actually said What I think others heard What others actually heard Our words cannot contain and convey all the information by design. That is why tone of voice, facial expression, and gestures fill in the gaps in our understanding. So, in every communication, we must add and allow a small bit of nuance, consideration, and intentional unclarity so that a “reasonable” amount of truth can sustain “reasonable” understanding with each other. We won't see the full picture of truth until we see Jesus as he really is (2 Cor 3:18). Then we will all know the truth in full, and it will make us live forever, instead of killing us. Only pure water that does not kill is Jesus himself, the living water. (John 4:13-14) It is because through Jesus came not just truth, but "grace" and truth. (John 1:17) Grace allows truth to be true without being cruel.

481. Power of Weaknesses
Continuing on last week's blog, I want to talk about another weakness. During my guest speaking engagement in Nashville, someone came up to thank me for the message and asked how I could be so precise and concise in my words and points. I'd never been asked this question in person, so I thought for a moment. I told her it is actually because of my weakness: I'm not gifted in speech, and English isn't my first language, so I have to write everything for my talk because I cannot wing it. And I don't have the Charisma or humorous presence some pastors do, so I need to be precise in my points to keep people engaged. But many people came to me during this retreat saying, "Pastor Caleb has a lot of bangers!" After almost failing OAC (Grade 13) English because of presentations, I found it delightful that God's power was most evident in my biggest weakness. We dread our weaknesses because they don't seem to have immediate merit. Weakness is a weakness no matter how you decorate it. Especially without God, it is easy to despair over our weaknesses. We find it hard to imagine how our weakness could become something good. But if we submit it to God, he can use it to turn it into strength, or to make it look like strength. Because he uses the weak to shame the strong. (1 Cor 1:27) It is not that God doesn't use our strengths. But his strengths become much more evident through our weaknesses. People find merit in embracing our weaknesses. But the Bible goes a bit further. We are not just to be open about our weaknesses; we are to "boast" about them. (2 Cor 12:9)
It doesn't mean putting all our weaknesses in CAPS on our resume boastfully. It means we believe God's greatest favour will land on our weaknesses, not our strengths, and accomplish what we never thought possible. You might not have a good family background. It could be your childhood trauma. It could be your personality or tendency. It could be your not-so-dramatic faith life. If we embrace it as part of our identity and believe in God's extra favour on it, our weaknesses don't become a blockage but a building block for God's power.

480. Benefit of Weaknesses
I came back last Sunday after preaching at Unity Baptist Church in Nashville. I usually preach on the theme "Abundant Life", and it has four sessions: Happiness, Identity, Purpose and Future. Interestingly, after the second session, when I preach about "Identity," which is based on our weaknesses, not strengths, people often come to me to share how they connected with my message and my weaknesses. In the session, I shared about my weaknesses, mainly my introverted personality and my speech. It seems to confirm what one leader said: "People will admire you for your strengths but connect with your weaknesses." We think of weaknesses as defects. But if we embrace them as "part" of our identity, not only do we feel authentic, but God also uses that to encourage people and connect with them. So, at one point, I began to be intentionally open about what I see as my weakness. What I shared recently was about my desire for good things (namely Apple products and Lululemon, which some people consider excessive spending), mainly because they bring "me" great joy while using them. Thankfully, many of my members appreciate that I share it openly. (I think) I used to try to be more frugal. I thought, "Why am I not as frugal as other pastors who seem to get by with very little?" I budget, and I try to manage our household finances based on biblical and sound financial principles. But I struggle to find satisfaction in using things I don't love. Some people are happy with any smartphone or computer, as long as it works. Not me. Some people are very happy with cheap, functional clothes. Not me. (By the way, not all my clothes are Lululemon!) I genuinely struggled, but I eventually embraced this as part of me. Because I sensed that God doesn't judge me for it, and He seems to joyfully satisfy me with the good things I desire, which matches what He promises. (Psalms 103:5) It doesn't mean that I now mindlessly spend money on them, but I stopped condemning myself for not being as frugal as others. Thankfully, the Bible emphasizes more about "generosity" than "frugality", which is what I try to focus on instead. In Exodus, there were two miracles in God’s provision. The first miracle was "Manna", bread God sent from heaven. The second miracle was that those who gathered a lot (because of their great appetite) had no leftovers, and those who gathered a little (those who don't eat a lot) had no deficit. (Exo 16:16-18) They all amounted to the same amount God prescribed for their collection: one "Omer" (about 2.2 L). God can satisfy both those who need a lot and those who don't. We think our weaknesses will drive away people. But they actually attract them. Only our weaknesses that are "found out" do. That said, don't compare your strength with someone else's weakness. That leads to pride. What matters is whether we receive whatever amount of God's provision with "contentment", not "comparison".

479. Only This Far
This post is a translation of Pastor Lee's post from SBC's website, written on 9.27. 2026. We use certain words and ways of thinking without much thought, yet they quietly diminish the potential of our spiritual lives. One of them, I believe, is the expression many Koreans often use: ‘Only this far.’ (여기까지) Some people say that this phrase accurately describes the faith of many Korean Christians today. For example, when they are asked to serve in a ministry, they set a limit for themselves and say, ‘This is as far as I can go.’ Even those who are serving as Shepherds and Shepherd’s wives sometimes draw an invisible line in their hearts and decide, ‘This is as much as I’m willing to do.’ As I heard people describe this tendency, I could not help but ask myself, “Are we any different?” As I reflected, I realized how such thinking can hinder not only the capacity God has given us but also the work He desires to accomplish through us. One lesson I have learned through ministry is that God has given us far greater capacity than we realize. Human capacity can keep growing as long as we are willing to stretch it. Someone who struggles to care for one person today may continue responding to the challenges God places before them and eventually find themselves caring for two hundred people. Mother Teresa is a good example. When my wife lived in Korea, she would become completely exhausted after preparing a meal for ten guests. Sometimes she would even get sick afterward. But while serving in a singles house church, there were times when she prepared meals for as many as forty people, attended early morning prayer the next day, and later, when our third worship service first began, she regularly helped feed 120 young adults after worship. Today, because of her severe vision loss, she can no longer do those things, but she has become someone who is no longer intimidated by large numbers of guests. God expanded her capacity far beyond what she once thought possible. The same principle applies to intellectual abilities such as memory, learning, and understanding. Human capacity grows as it is stretched. We can be used far beyond what we believe our limits are. In fact, I believe this is part of what Jesus intended to teach through the Parable of the Talents. The servant who buried what he was entrusted with and returned it unchanged was called a wicked and lazy servant. In the same way, if we keep standing before opportunities for ministry and saying, “Only this far,” drawing our own boundaries, I believe we will one day hear a similar rebuke from our Lord. This mindset not only limits our own capacity; it also limits what God can do in and through us. Peter was the only disciple who stepped out of the boat. Even if he walked on water for only a few steps, he experienced something the others never did. Had he stayed in the boat, he would not have experienced a miracle. When we step beyond our comfort zone and take a risk in faith, God works, and we get to witness His work firsthand. When circumstances seem impossible, and we choose to tithe anyway, we discover God’s surprising provision. When life seems too busy and overwhelming to become a Shepherd, yet we commit ourselves to that ministry, we encounter God’s work in our lives. When we are sick, the natural response is to visit a doctor, but sometimes, when we step forward and ask for prayer, we experience God’s healing power in a fresh way. If we act only according to what seems reasonable and safe, we leave little room for God to demonstrate His power. It is when we step beyond what appears sensible and take a step of faith that we often experience God at work. But if we keep saying, “Only this far,” we will inevitably place limits on what God desires to do. Therefore, whenever the words “Only this far” begin to come out of your mouth, stop yourself. Instead, say, “If God desires it, I am willing to go the extra mile.” As you do, may God expand your capacity and enlarge your territory, and may you experience His wonderful work in your life.

478. Under Authority
These days, it's easy to find people who don't want to work for anyone. They want to be their own boss because they hate being told what to do. It is natural for humans to want independence, but if we are not careful, we might end up with no authority above us. It happens a lot as we get older, but it can also happen to young people once they reach adulthood because they now have a choice. But having no authority above us is not only impossible but dangerous. I heard someone say the most dangerous person is someone with no one above him. Some people might reach the top of the corporate ladder and have no official boss. But being under authority isn't just about having someone to report to; it's about seeking their counsel. That is why wise CEOs seek counsel and look for mentors with more experience than they do. Many people like the idea of humility but hate being under authority. But the best way to keep ourselves from becoming proud is to submit to someone ahead of us. I have Pastor Kwack as my authority, and I submit under his leadership. I submit to a leadership team on big ministry decisions (though we also submit to each other) and seek their counsel. I have many pastors in the house church network who have no official title above me, but I also submit to their authority because of the ministry journey they took ahead of me. I ask them questions before launching something big. The most tangible way to measure our humility is to ask this simple question: Do I have leaders whose advice I seek before making a big decision? If we don't, we might be spiritually in a dangerous place. I’m not talking about leaders or influencers we follow on Instagram, authors of books we read, or podcast hosts we listen to. I’m talking about real people around us who are ahead of us (other than our parents). When no one is involved in the important decisions of our lives, we might have people with titles of leaders, but we are not under real leadership. Under the right authority, we will always recognize what we lack and seek help. If we have one, we will appreciate feedback and be thankful for it. If we don’t, we will be offended when truth is spoken over us, because we won't see the need for it. We always have to be under someone. Some might say, “I’m under God’s authority!" That is a clear example of loophole-Christianity. Even the Son of God submitted to the Father God. It's a spiritual-sounding way of saying they don't like being under authority and want to stay proud.

477. How I Use AI
During the HC pastors' conference, as we ate breakfast, one of the pastors brought up the issue of "AI-generated worship songs" playing in some churches. So the discussion began, focused on "how much is too much." It was an interesting but also thought-provoking conversation. AI is the hottest topic wherever we go, and no one can doubt how prevalent it is these days. Even many seniors who are not tech-savvy regularly use and rely on AI. Many church members also use AI to get faith-related advice. So it is not hard to guess that many people are also curious about how pastors use AI and "how much." I can't speak for other pastors, so I will be transparent about how I use it. The first time I used AI extensively wasn't for my work, but for travel planning during my Japan Trip in 2024. I realized how much time it saved, as it gave me popular routes instantly without me having to compare different reviews and social media content. Then I thought about how I could use it more in my ministry. I tested it by asking it to give me exegesis of a certain passage to see if it says anything weird, but surprisingly, its output was pretty sound. So I started incorporating it into my sermon research for more modern implications. But AI is "one" of the resources I use. I usually study 3 commentaries, so it became my 4th resource. These days, I am trying to use it more to search my own work. I have my past sermons, blog posts, and new ideas all in a deposit of text files. The amount is quite large, and searching them manually has limitations. Now, I can ask AI to search my past work for a specific theme or words and use it to build a starting block for a related talk or message (usually for guest preaching). I find it useful because it can dig through my own work and synthesize a new creative direction. AI is also very handy for grammar checks. As English is not my first language, I try to make sure my main points are grammatically error-free. Sometimes they can be too wordy, unclear or potentially misleading, so I ask AI for correct expressions. But I do not ask AI to generate my main point. Whether AI is a net positive is hotly debated, even among experts. I am also in the middle of researching and experimenting. Meanwhile, what I can do now, at least, is maintain my "agency", not allowing it to "do" my work but to "assist" me. One thing I am sure of is that preserving our own agency will remain the greatest challenge when it comes to AI usage.
