The Philippian jailer once asked, "What must I do to be saved?" (Acts 16:30). If Paul had been an extreme Calvinist he might have said, "You can do nothing to be saved, absolutely nothing. You are dead in sin and a dead man can do nothing. If God doesn't regenerate you, then you are doomed." How different was the answer Paul gave: "Believe on the Lord Jesus Christ and thou shalt be saved" (Acts 16:31).
It seems to me that when Jesus walked the earth and after He ascended into Heaven men were taught to believe upon Jesus. It was enough to believe. That was the true sign that one was a Christian. There was a direct correlation between belief and faith in Christ
It seems after free-will controversies, it was no longer acceptable to simply believe. You could no longer simply be a professor who has faith.
Believing the gospel, trusting and having faith in Jesus are true signs of being regenerated, correct? I think that is the main point the author is making. That we need not wait around hoping God will regenerate us. The fact that we believe and have faith is evidence that we are regenerate.
