You cannot build your life with a consistent worldview that is on the shifting sands of moral relativism.

There's no way you could convince me today that Jesus is not real.

Often it is hard. So hard, in fact, that Jesus' decree to love and pray for our opponents is regarded as one of the most breathtaking and gut-wrenching challenges of his entire Sermon on the Mount, a speech renowned for its outrageous claims. There was no record of any other spiritual leader ever having articulated such a clear-cut, unambiguous command for people to express compassion to those who are actively working against their best interests.

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.

Paul said in I Corinthians 15:17, if Christ has not been raised, your faith is futile. So that's the linchpin of the Christian faith, is whether Jesus did indeed, A, live, B, die, and C, was resurrected from the dead, which authenticated his claims of divinity.

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

Faith is taking a step in the same direction that the evidence is pointing.
