In OT, full knowledge of God comes through actively doing his will. But saved when he believed. In NT, example of Peter. He drops net and follows Jesus. Only later does he put faith into words.
Resolutions peter out fast.
B. Do something concrete. Those who get involved early are more likely to stick. The kind of actions that build faith. Only few do it, but God holds accountable. It is a real test, because we only give to what we truly believe in.
