Some think men have a lot of power (while being spiritually dead in sin and incapable) and with it have the ability to choose themselves out of and into the grace of God at will. Jesus says man is not able; John 6:44, John 6:65.
Romans 8 also says the same things in 8:5ff, speaking of man's inability. This passage was of course given by inspiration of the Holy Spirit well after people started misusing the verse in John 12:32 to say all men have ability.
Nope.
If man had the ability, then salvation is not 100% of God, it is part man, part God.
And frankly? That isn't biblical or true Gospel teaching because salvation is 100% of God.
John 1:13 shows we are not saved via our wills by any means whatsoever. So does Romans 9:16.
James 1:18; Ephesians 1:11; John 6:63 and other Scriptures show we are saved via God's will. The only way in which salvation has anything to do with choosing is in the fact God chose us. Note also 1 Corinthians 1:26-31.
