“No one understands!
No one seeks God!”
οὐκ ἔστιν ὁ συνίων, οὐκ ἔστιν ὁ ἐκζητῶν τὸν Θεόν·
Paul said that no one understands (οὐκ ἔστιν ὁ συνίων). There is no one who seeks God (οὐκ ἔστιν ὁ ἐκζητῶν τὸν Θεόν). Once again Paul referenced Psalm 14:2 and Psalm 53:3. Yahweh was looking for the wise ones. He wanted to see if there were any who were wise, seeking God. Yahweh was perched in heaven looking down at all the humans. The concept of the wise person is the one who seeks God. Thus, the wise man would seek God. Only the foolish ones did not understand or seek God. The evil doers were stupid. Do you consider evil people as stupid?
