I don't know how many times I've seen 1Cor 2.9 misused to mean something it doesn't signify.* The text says, 'But as it is written: "Eye has not seen, nor ear heard, Nor have entered into the heart of man The things which God has prepared for those who love Him" ' (NKJV). This seems to be a composite quote or allusion to Isaiah 64.4; 65.17; 52.15 (as we have no direct OT quote according to Robertson . It may also be that Paul alludes to the rendering of the Septuagint, a translation of the Hebrew scriptures into Greek.) Verse 9 is often quoted with the speaker finishing at the end of verse 9. The problem with this 'ending' is that it gives us a reading that distorts verse 9 because both the larger and immediate contexts are ignored.
we look not to the things that are seen but to the things that are unseen --Paul, Apostle to the Gentiles
