⁹ However, as it is written:

¹⁰ these are the things God has revealed^(B) to us by his Spirit.^(C)

The Spirit searches all things, even the deep things of God. ¹¹ For who knows a person’s thoughts^(D) except their own spirit^(E) within them? In the same way no one knows the thoughts of God except the Spirit of God. ¹² What we have received is not the spirit^(F) of the world,^(G) but the Spirit who is from God, so that we may understand what God has freely given us. ¹³ This is what we speak, not in words taught us by human wisdom^(H) but in words taught by the Spirit, explaining spiritual realities with Spirit-taught words.^[b]

¹⁸ So we fix our eyes not on what is seen, but on what is unseen,^(A) since what is seen is temporary, but what is unseen is eternal.
