Two thousand years ago a man lived in what is today the country of Israel. He was a Jew and a carpenter by trade. He never traveled far from home, never wrote a book, never raised an army, and never served in any political office. But amazingly, incredibly, he claimed to be the Messiah and Son of God. He lived a perfect life and performed miracles, healing the sick and lame, giving sight to the blind, walking on water, even raising the dead, the kinds of things one would expect the real Son of God would be able to do.
There were those who considered his claims blasphemous, and they executed him for this crime, just as he had predicted (along with the Old Testament prophets centuries before). Three days later he rose physically from the dead, proving convincingly that he was who he claimed to be, and that is how and why he is now our Savior. The person of the Son of God, by taking on a human body and living a perfect life, by suffering with us and dying for us, and by overcoming death itself, has reunited us with our Creator. This is truly good news. God loves us, he knows our pain, and he has provided the means for sinful men and women to have true relationship with a holy God. These are the facts, and believing these facts is, in the most basic sense, what makes one a Christian….
We do not claim to have all the answers. But we have more than enough to show that our faith in an omnipotent, omniscient, holy, and loving Creator God, who bridged the gap between himself and humankind in the person of Jesus Christ, is not only reasonable but is, in fact, the most intellectually and existentially coherent option among all others. Christianity is both sensible to the head and satisfying to the heart.
