I’ve seen far too many Christians who are more than willing to travel halfway around the world to volunteer for a week in an orphanage, but who cannot bring themselves to take the personal risk of sharing Jesus with the co-worker who sits day after day in the cubicle right next to them.

Of course, there are always going to be some unsettled areas, but for me the overall evidence for Christianity chases away any real doubt that it's true.

I do know plenty of atheists, agnostics and skeptics who have become Christians through the years. In fact, several of my friends were once strong atheists but are now committed followers of Jesus.

Doubts can produce positive side-effects - if you work toward resolving them.

I'm all for lifestyle evangelism, but I'm also in favor of intentionality, where we seek out opportunities for spiritual conversations and are equipped to explain the gospel and why we believe it.

I have a good Muslim friend who comes over to my house. Good guy; reads the Qur'an in Arabic. He comes over to my house and we talk about faith and we talk about things we have in common, but I can't shy away from the differences that we have. So I talk about why I'm not a Muslim and about the evidence that exists that show Christianity is true.

For me, apologetics proved to be the turning point of my life and eternity. I'm thankful for the scholars who so passionately and effectively defend the truth of Christianity - and today my life's goal is to do my part in helping others get answers to the questions that are blocking them in their spiritual journey toward Christ.
