Know What You Know

Sep 13, 2026  •  Paul McGinnis

What does it mean to truly know something? Not just to have heard it, or read it, or nodded along with it, but to know it so deeply that no argument, no challenge, and no season of doubt can shake it loose? That is the heart of what we explore in this message. We live in a moment when the voices competing for our faith are louder than ever, when culture is shifting beneath our feet and the morale of believers is being tested. And yet, the answer is not to know everything. It is to know what we know. The central anchor of this message comes from 1 Peter 3:15, where believers are urged to always be ready to give a reason for the hope that lives inside them. This was written to Christians scattered across a hostile world, people experiencing rejection and suffering for following Jesus. The instruction was not to become scholars of every argument, but to be grounded enough in their experience of God that they could speak with confidence. The word translated as defense in that passage gives us the root of the word apologetics, which is not about apologizing for our faith but about being prepared to explain and defend it. That distinction matters enormously. We are not called to shrink back. We are called to stand firm, not in arrogance, but in the quiet confidence of people who have walked with a faithful God and seen Him come through.
