(Mark 8:27–30)
It’s the most important question anyone can ask—and answer: “Who do you say that Jesus is?” (Mark 8:29). Jesus asked it to His disciples in Caesarea Philippi, a city filled with temples and idols—an intersection of religious and political power. Surrounded by rival gods, He looked at His closest followers and pressed the question home. He started by saying, “What do others say about me?” but that was a bridge question. The real question that mattered in that moment wasn’t what other folks said about Jesus, but them, his disciples “Who do y’all say that I am?”
That same question confronts every one of us. How you answer it will shape every other part of your life—what you believe, how you behave, and what kind of person you become.
If Jesus is simply a good teacher, then His words are just one voice among many. If He’s merely a moral example, then you can admire Him but still ignore Him. But if He is who He claimed to be—the Christ, the Eternal Son of the Living God—then everything changes.
What You Believe About Jesus Shapes Everything
What you believe about Jesus will determine how you live. If He’s Lord, then He has the right to speak into every part of your life—your choices, your desires, your priorities.
How you answer that question will determine:
- How you view alcohol—Will you abide by the God appointed law of the land (Romans 13) and wait until you are 21? Should you consume it at all? And if so, will you do so wisely in gratitude to God or use it as an escape (Ephesians 5:18)?
- How you engage in sex—Will you engage in sex as it was given from God–to a covenant husband and wife til death separates? Then within the marriage, will you treat it as sacrificial, holy, covenant love or selfish indulgence (1 Thessalonians 4:3–5; Hebrews 13:4)?
- What you do with money—whether you see it as yours to spend or God’s to steward (Matthew 6:21, 24).
- How you parent—whether you seek to impress others or to point your children toward Christ (Deuteronomy 6:6–7; Ephesians 6:4). Will you let the Gospel shape your kids’ hearts or will you simply engage in behavior management?
- How you act when no one’s watching—whether you cut corners or walk in integrity (Proverbs 10:9). Will you choose to cheat on the test or trust your preparation?
- How you treat people—both to their face and behind their back (Matthew 7:12; Ephesians 4:29).
When Peter declared, “You are the Christ,” he wasn’t just identifying Jesus; he was confessing a commitment of his life to Him. Confessing Jesus as Lord means surrendering every part of your life to His authority.
The Choice C.S. Lewis Set Before the World
In Mere Christianity, C.S. Lewis famously wrestled with this same question. He wrote:
“I am trying here to prevent anyone saying the really foolish thing that people often say about Him: ‘I’m ready to accept Jesus as a great moral teacher, but I don’t accept His claim to be God.’ That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic—on the level with the man who says he is a poached egg—or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God: or else a madman or something worse… But let us not come with any patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.”
Lewis spoke those words during WWII in the early 1940s, not first in a book, but over BBC radio to a war-weary Britain. Bombs were falling on London. Fear, doubt, and disillusionment filled the air. In that context, Lewis offered not sentimentality, but clarity. If Jesus is Lord, then hope is real, forgiveness is available, and evil will not have the last word.
That’s why his argument still matters. Jesus can’t just be admired; He must be either rejected or worshiped. There’s no neutral ground.
The Question Still Stands
When Jesus asks, “Who do you say that I am?” He’s not seeking information; He’s seeking transformation. It’s a question that cuts through the noise of our opinions, politics, and preferences.
Some say He was a prophet. Others, a revolutionary. Some call Him irrelevant. Others use His name as a brand. But Jesus is still asking: “Who do you say that I am?”
Your answer will shape everything.
So Reflect. Consider. And commit. Don’t settle for secondhand opinions or borrowed beliefs.
Answer Him in your heart and with your actions. Confess Him with your lips and your life.
Because if He truly is the Christ, the Eternal Son of the Living God—then He deserves nothing less than your whole heart, your whole life, and your full allegiance.
