Proverbs 21:27
The sacrifice of the wicked is abomination: how much more, when he bringeth it with a wicked mind?
Do you know that the LORD searches the intentions of the heart and not your scarifices? He does not search how much or how costly sacrifices you bring to Him? You can fool man with your sacrifices but you cannot fool God. God allows you to go on fooling others until the day comes for you to be rebuked and punished after many warnings. The wicked also bring sacrifices to God because they feel guilty of their sins. But, just because you feel guilty, it may not mean that you have repented of your sins. It is easier to offer sacrifices than to truly repent of your sins. Truly repenting is offering yourself fully to Him and that is harder to do. You would have to remain obedient to Him all throughout. It's easier to just offer sacrifices and walk away to continue committing the same sins again and again out there. Whom are you trying to fool? You can fool men who are just like you, but you cannot fool God who knows what is hidden in your heart. He knows the wicked as well as the righteous of the LORD. He knows what's in your mind. The sacrifice of the wicked is abomination to Him. So, don't keep repeating your play-acting. He knows it all! The day will come for you when you will be punished for this.
Luke 16:15
Then he said to them, "You like to look good in public, but God knows your evil hearts. What this world honors is an abomination in the sight of God.
