I think that it is not the will that predestination concerns itself with, but desires.<br><br>It is possible to remain sinless for the whole of one's life. However, due to human nature, we desire only to do evil. Thus, sinlessness is only hypothetical; man's evil desires prevents him entirely from being sinless.<br><br>When God redeems us, he changes our desires so that we want to serve him. Thus, the only reason why are willing to follow after Christ is because we desire him. This desire is entirely a work of the Holy Spirit; thus, it is a miracle that we desire God at all.<br><br>Hence, IMO, the will is not as important as desire when it comes to the doctrine of predestination.
