God could reject our worship for a number of reasons. He specifically condemns acts of worship associated with idolatry, unbelief, disobedience, and evil motives (Jeremiah 13:10; Exodus 30:9; 32:22-27; Jeremiah 7:21-26). Rehearsing this list makes me aware that our offerings of worship will never please God on their own. Try as hard as we can, our hearts and worship will always be tainted in God’s sight. The ultimate factor of acceptable worship is faith in and union with Jesus Christ. Our spiritual sacrifices are “acceptable to God through Jesus Christ” (1 Peter 2:5). It is His sinless offering of worship that cleanses and perfects ours.
