a. God long ago made a provision for your salvation, but Christ does not do anything for you until you "accept" Him. Thus the idea is conveyed that if you are saved it will be due to your own initiative. And if you are lost it is God who will take the initiative in punishing you.
b. God has made a provision for your salvation but that does you no good until you "accept Christ." Egocentricity distorts and colors all concepts of justification. This is inevitable when the sinner is taught that everything depends on what he does about Gods offer.
c. Christ has justified all men; the "good news" tells them so. By the Spirit He actively and persistently "draws" all until they beat Him off by persistent rejection. The "good news" is not IF you do your part, but if you truly appreciate what HE has done (have faith). True acceptance is real faith.
