Vs. 1, “The fool says in his heart, “There is no God.” They are corrupt, and their ways are vile; there is no one who does good.” Does this look familiar? It should, because it is almost the same as Psalm 14. This psalm is a reiteration/adaptation of the previous. Some psalms were purposely adapted for various uses in the temple worship. We see how the same Scripture can be applied in different kinds of situations.
Regarding application…Who is The Fool? No, it is not a stupid person…on the contrary, it is one who is perhaps too smart for their own good. Most in this world will not deny the existence of God. (My personal belief that Atheists are only trying to convince themselves there is no God)….Anyways…since most do not deny the existence of God…the fool would be a person who does not deny the existence of God…yet lives as if there is no God. That can be termed as a “practical atheist”. We were all practical atheists at one point in our lives…but at some point we went from “fools” to “God’s beloved” when we stepped out in Faith in Christ. While it is true, there is no one that is righteous (Vs.3)…when we submit our wills unto Him…we become the rightousness of God! Live today as one who not only knows….but lives like there is a God!
