Proverbs 15:8: "The sacrifice of the wicked is an abomination of the Lord, but the prayer of the upright is His delight."
You'll notice, both are offering an act of worship to the Lord, but one is an abomination and one is a delight. Why do you suppose a wicked person would offer an act of worship? There are likely numerous reasons why, but it might be an attempt to bribe the Lord; to manipulate His will. God doesn't do business that way! The only thing God accepts as worship from the wicked is repentance. Unless or until the disobedient repent, they live in opposition to God - and that certainly includes any act of worship that comes from a rebellious heart.
