It must be the power of God. For this reason, we often hear that the power of God manifested in the salvation of one man far exceeds the power of God manifested in the very creation of the universe. God created the world ex nihilo, out of nothing. However, when God saves a man, He does an exceedingly more difficult thing. It is far easier to create good out of nothing than it is to recreate good out of a fallen and corrupt humanity.
