Holier than Thou

I cant stand people who go to church on Sunday shouting hallelujah up and down whilst have acted a FOOL Monday through Saturday and although GOD may be a forgiving God, He surely can see through the "fakeness".
The worst part of it all these are the same people who are the first to judge somebody else. Sad thing is ...I know atheists who are more morally righteous than some people I've met in churches. SMH
