This fall in Youth Group we’re talking about various worldviews. Last Sunday night we discussed the Christian worldview. As I was making up the presentation, it occurred to me just how easy it is for us to lay out what we believe in writing. I can tell you that God created the world and that mankind bears the image of God (though fallen as we are). I can tell you that God is triune and that Jesus, the Son, died on the cross for our sins. I can tell you about the resurrection and the hope to come.
The problems really come in when we start to think about what all of those things mean for us in our own lives. That’s much harder.
Indeed, it doesn’t take long for us to see that we do not live consistently with the worldview that we profess. We might believe that we are accepted by God through the blood of Christ, but we often find ourselves living out of a place of fear, worried that God displeased with us. Our theology teaches us that Christ will one day make all things new, but we still approach so many things with cynicism.
One of the interesting things, though, is that our worldview accounts for us living out of accord with our worldview. Paul says in Romans 7, “I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members.” The Christian worldview recognizes that we are sinners saved by grace. God knew that sin runs so deep in us, that we would continue to walk in ways contrary to what we even know to be true. The good news is that he loved us anyways.
And here is the thing that’s really amazing about the Christian worldview: the more you meditate on the truth of the gospel — that Jesus died for you; that you are adopted by God; that, despite your sin, he loves and accepts you — the more you come back to the truths of the gospel, the more they shape your behavior. In other words, the more you rehearse the truths of the gospel in your heart, the more you believe it, and the more you believe it, the more it begins to work into the fabric of your life, and the more you begin to live in conformity to what you really believe.
It’s not enough just to say that Christianity is true; you really have to live it. But, in a way, the more you say Christianity is true, the more you will live it.
