Psalms 14:3

All human beings have turned aside from the wise way of fearing the Lord (cf. Genesis 6:5-6; Genesis 11:1-9). The result is that they have become corrupt (Heb. alah, lit. sour, like milk) morally. Not one solitary individual does good in the sight of God on his own initiative and in his own strength (cf. Romans 3:23). It is for this reason that no one can be acceptable to God on the merit of his own works. All need the goodness (righteousness) that only God can provide for us.
