Dang that word "CANNOT"! That word needs to be severely watered down -- which FWers are all too eager to do.
Romans 3 verses 11-12; Romans 8 verses 5-8; 2 Timothy 2 verses 25-26 There is no one who understands, no one who seeks God. All have turned away, they have together become worthless; there is no one who does good, not even one. For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot. Those who are in the flesh cannot please God. God may perhaps grant them repentance leading to a knowledge of the truth, and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will.
