For we are not saved by believing in our own salvation, nor by believing anything whatsoever about ourselves. We are saved by what we believe about the Son of God and His righteousness. The gospel believed saves; not the believing in our own faith.
It is true that we need to make a onetime decision to follow Jesus. But a true onetime decision is followed by the everyday decision tofollow Jesus.
Hope is an enthusiastic assurance.
We are no more secure in Christ with a strong faith than with a small faith, so long as that small faith is true faith.
