“The Reformers believed that the will, although in a fallen state, could still achieve civic virtue or civic righteousness. Fallen man can still obey the traffic lights and so on, but he cannot incline himself to the things of God. Jesus said, ‘This is why I told you that no one can come to me unless it is granted him by the Father’ (John 6:65). ‘No one can’ means that no one is able. One of the key doctrines of the Reformation was sola gratia, meaning that we are saved by God’s grace alone and not from our own efforts. Does fallen man have the ability to turn to Christ and to choose Him before he is born of the Holy Spirit? Most professing evangelical Christians today believe that faith comes first and then rebirth. This presupposes that the unconverted person has the ability to incline himself, or choose to come, to Jesus Christ. Augustine, Luther, Calvin, and Edwards said that no one is able to do that. If we continue to think that in our fallen state we have the moral ability to come to Christ apart from the grace of God, we do so at our own peril. In John 6:65, our Lord clearly says that no one is able to come to Him unless the ability to do so is given to him by the Father. Fortunately for us, Jesus puts the word ‘unless’ in the statement. That word points to what we call a necessary condition, a sine qua non. A necessary condition has to be met before a desired result can occur. The desired result is coming to Christ; the necessary condition is that the ability to come must be given to each person by the Father. Only God gives that ability. No one can come to Christ on his own; we are not able to, unless God gives us the moral ability to do it.” (Sproul, Truths We Confess, 235-236)
