9However, as it is written: “What no eye has seen, what no ear has heard, and what no human mind has conceived” Isaiah 64:4 — the things God has prepared for those who love him—
10these are the things God has revealed to us by his Spirit. The Spirit searches all things, even the deep things of God. 11For who knows a person’s thoughts except their own spirit within them? In the same way no one knows the thoughts of God except the Spirit of God. 12What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us.
