"A fool has said in his heart, there is no God. They are corrupt, they have done abominable works, there is none that doeth good."
A practical meaning is that there are some that will say that God is not real, because he doesn't respond they way they think that he should, or because he doesn't stop horrible things from happening to innocent people. They apparently have been taught some sort of fairy tale about us humans living in a magic kingdom of everything is good and God is supposed to stop all bad stuff from happening. Not only is that NOT biblical, it is NOT biblical.
And since they don't believe and therefore don't live for God,the works they do (even the good works) don't give God any glory, so those actions are classified as 'abominable'!! Remember that God created us to do good works and give him the glory, so anyone taking the credit for themselves is stealing credit from God!!
When you consider the people who don't believe in God, you won't find them giving God the Glory - because they don't believe, and this is why it says that 'none' of them are doing good. Even their good actions aren't biblically good, because God is not getting any credit. Might be real nice works, but no praise is going to God for it.
So consider what you do and make sure that you give honor and credit to God, because you wouldn't have any of the abilities or skills that you are used to, you wouldn't understand the deeper things of God, unless God had blessed you in the first place! And please remember, serving God helps make everything better -even the bad stuff !!
With Love
