When I was in high school I had a graphic design class. To my left sat a guy I'd known for about four years. He was an outspoken atheist and pretty much everybody knew it. One day out of nowhere it just popped into my mind to ask him, "Hey, why don't you believe in Christ?"
He looked at me and said there were two reasons.
The first: he didn't really believe that any of us believed it either.
That caught me off guard. I'd been a Christian my whole life. Baptized in second grade. How could I not believe in Jesus?
He kept going. "Which leads me to reason two. Because if all of you did believe, then that means that for the last four years, everyone at this school who claims to be a Christian must hate me so much that not one person until this moment has even asked why I don't believe, much less tried to share the gospel with me. And if it was true, and you did believe it, how could you not spend every waking moment trying to share it with every single person you could?"
I still think about sitting at that desk looking him in the eyes as he said that.
Because at the root of what he was telling me was that it wasn't clear from my life that I believed what I said I believed. The urgency wasn't there. The love wasn't there. Romans 10:14 asks, "How are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?"
He had been sitting four years in school with people who said they followed Jesus, and nobody had ever said a word. That's on me. I had missed the urgency of the Great Commission entirely. I had missed the fact that following Jesus means, by definition, pointing others toward Him. And I don't want to make that mistake twice.
