As it is written: “None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one.”
Romans 3:10-12

The original in Psalm 14:1-3 was an emotional outburst, intended to be understood as hyperbolic. It's not technically true that nobody is righteous, understands, or seeks God. Rather, nobody is sufficiently righteous, sufficiently understanding, or seeks God diligently enough. Everyone has gone astray, even if in some small way. Everyone is worthless and no good compared to Yeshua.
