I believe as you do that we all are given the ability to "Choose" but I believe that ability comes from God as Jesus states in John 6:44,65 We are all born in sin so our natural instinct is to sin, unless that nature is changed (and we are powerless to change it) we will continue to reject all that Christ has done and is constantly doing for us, for the human mind is so inferior to that of GOD that being carnal we can't, or have no desire to, accept His Grace, for we are told that "We are saved by Grace through Faith but this is not of our own, it is the gift of GOD lest anyone should boast" those of us who "choose" to accept that Grace will be given it "if we seek it with all our heart" we are being Sanctified but still have a long way to go....Ray
I do agree that even this is from God.
Only I also think we should not judge that someone, because they do not walk in the new nature, are certainly evil. Rather, they are fallen, like all humans. But they may, though they be weak in righteousness, still chose it, and love their neighbor, therefore fulfilling the law.
As for us, we receive grace freely... But for a purpose, that we might run the race. If men can be righteous without the new nature, how greatly our righteousness should exceed theirs if we have the very nature of Christ given to us! We are given more, and thus more is expected.
