Ah, so Abraham's justification was NOT one moment, was it...
Glad to see you got the point.

Sorry to see that you missed the point.
Abraham is saved when he first believed (Rom.4:3) and then grows in faith, showing that faith until his last test in Heb.11:17 where he is tried and passed then shows his close relationship with God, being called God's friend.(James 2)
By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh (Heb.11:4).
Faith gives witness what one believes, by working, but works do not add to the faith, they are a result of it.
