Man does not have the ability in and of himself to come to Christ

No human being can possibly come to Christ unless something happens that makes it possible for him to come. That necessary condition Jesus declares is that ‗it has been granted to him by the Father.‘ Jesus is saying here that the ability to come to him is a gift from God. Man does not have the ability in and of himself to come to Christ. God must do something first.
