God which you heard from us, you accepted it not as the word of men but as what
it really is, the word of God, which is at work in you believers.

that is, the word of faith, which we preach.

“I have yet many things to say to you, but you cannot bear them now.
When the Spirit of truth comes, he will guide you into all the truth;

and he will declare to you the things that are to come.”
John 16, 12-13
