Psalm 51:11 “Do not cast me from your presence or take your Holy Spirit from me.” The worst experience anyone could possibly have is for God to remove Himself from anyone’s life.  To be deserted by God would be disaster eternally.  Doesn’t everyone realize the seriousness of ignoring or rejecting or choosing gods other than the True God?  Many don’t is the ultra-sad truth.  Our Psalmist realizes that ultra-sad truth as should you and I.
