Cyril of Alexandria

Human beings choose their own way of life and are entrusted with the reins of their own intelligence, so as to follow whatever course they wish, either toward the good or toward the contrary. But our [original, created] nature has implanted in it a zealous desire for whatever is good and the will to concern itself with goodness and righteousness. For this is what we mean by saying that humanity is “in the image and likeness of God,” that the creature is naturally disposed to what is good and right.

For that He utterly abolished death, and effaced destruction, and spoiled hell, and overthrew the tyranny of the enemy, and took away the sin of the world, and opened the gates above to the dwellers upon earth, and united earth to heaven: these things proved Him to be, as I said, in truth God.
