The reason coin:
Theism has an idea of what a god is. It then turns to look at the world and finds its idea more or less confirmed. Atheism has an idea of what a god is. It looks at the world and finds its idea more or less unconfirmed. Theism and atheism are two sides of the same coin – matching up an idea of god with what is seen in the world.
The revealed Christ:
Rather than humans projecting an idea of what a god is like onto observations of the world ((natural theology – whether theistic or atheistic in conclusion)), in Christianity, God reveals himself to us fully and finally in Christ. This revelation is surprising. Our logical ideas of god (powerful, glorious, etc.) are shattered by the dying, bleeding, weak, self-sacrificing, humiliating, suffering-with-us God of Christ and His Cross.
