One of the most convincing arguments for Christianity for me is how bizarrely counter-intuitive it is. It is a crazy Alice in Wonderland religion that turns “normal” ideas on their head!
What person would have been able to invent a religion where paradox is paramount? Where the more you give, the more you gain? Where the rich are poor and the poor are rich? Where dying (to yourself) is living and living (to yourself) is dying? Where you have to give everything up to gain the whole world? Where you treat your enemies like your friends, instead of exacting revenge on them? Where you love those who hate you and hate those who love you? (The last in the context of loving Christ Jesus so much that you are willing to disregard or abandon those you love to follow His will.)
