But as it is written, Eye has not seen, nor ear heard, neither have entered into the heart of man, the things which God has prepared for them that love him.
All Commentaries on 1 Corinthians 2:9 Go To 1 Corinthians 2
Tertullian of Carthage
AD 220
The expression means the blessings which await the flesh when in the kingdom of God it shall be renewed, and made like the angels, and waiting to obtain the things "which neither eye hath seen, nor ear heard, and which have not entered into the heart of man."
