There is no one who does good, not even one

Psalm 14:1-7
The fool says in his heart, "There is no God." They are corrupt, their deeds are vile.
The Lord looks down from heaven on the sons of men to see if there are any who understand any who seek God.
All have turn aside, they have together become corrupt; there is no one who does good, not even one.
You evildoers frustrate the plans of poor, but the Lord is their refuge.
Salvation for Israel would come out of Zion!
Society is corrupt: the bias to sin universal.
In wilful blindness humans pit themselves against a God who not only exists but punishes and avenges every aggressive act against his people.
Why?
There is God in heaven, he is our salvation, He is refuge to his people.
God is there who knows the heart of each one.
Paul uses these verses to support his case that no human being is sinless when measured by God's standard.
The psalmist calls the nation by the two names of its founder. They wily詭計多端的 Jacob was given the new name 'Israel' after his momentous重大 encounter with God at Peniel.
How?
Everyone has to confess his sin before the Lord, God is my refuge and salvation.
