When Paul gave evidence of his faith, he laid out what may be the primary proof the Apostles also pointed to: What we are saying perfectly lines up with what all the previous prophets predicted.
In his letter to the Galatians, one of the ways the Apostle Paul defended the gospel was by pointing to three ways he experienced Jesus in his personal life. While you probably haven’t seen a visible manifestation of the resurrected Jesus like Paul did, if you’ve really met Jesus, these things will be true of you, too.
The question, “Why is there something rather than nothing?” has occupied philosophers for centuries. It’s a tougher question than you might initially think. Where did all this stuff come from? Or has it always just been around? One thing is for certain: The created world is incredibly complex. In fact, scientists have long pointed out the sheer improbability of the complexities of life forming out of a mute, unguided chaos.
In a world filled with ascribed values, we can’t meaningfully call people to fundamental standards of right and wrong. For atheists, a statement like, “You truly ought to” or “ought not to” doesn’t really have any meaning. Of course, this doesn’t mean atheists can’t be moral, just that their morality lacks a consistent intellectual foundation. They have a difficult time finding a place for their “ought” to stand.
In a godless universe, every decision you’ve ever made is an illusion. You might think you “chose” to marry your wife, or quit smoking, or move to Raleigh. But remember, without God there isn’t really any you to speak of. Your biology made you do those things, and your mind just tricked you into thinking it was voluntary. How does that sit with you?
If biology is all there is, then death is the absolute end. As the famous atheist Bertrand Russell said just before his death, "When I die, I will be consumed by darkness. There is no splendor, no vastness anywhere. Life is only triviality for a moment and then nothing." Russell meant for that to be beautiful. I wonder how many of us can accept that and not find life crushingly horrifying.
