However, as it is written: "No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him"a1--
but God has revealed2 it to us by his Spirit.3 The Spirit searches all things, even the deep things of God.
For who among men knows the thoughts of a man4 except the man's spirit5 within him? In the same way no one knows the thoughts of God except the Spirit of God.
We have not received the spirit6 of the world7 but the Spirit who is from God, that we may understand what God has freely given us.
This is what we speak, not in words taught us by human wisdom8 but in words taught by the Spirit, expressing spiritual truths in spiritual words.b
