It is impossible for fallen man to choose God,
There is no desire to know Him, God must draw (drag) him.
So you can think that you chose to believe but without God dragging
you to Him, you would not, and could not believe.
Joh 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
Joh 3:20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
Joh 3:21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
