Everyone has sinned against God. Publicly or privately. You are instructed in the Word of God to confess that sin and turn away from it. Do it now. Obey Him.
Only a fool would attempt to deceive God. Your confession will unlock God’s mercy.
“He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.”
(Proverbs 28:13)
