“Therefore if you are presenting your offering at the altar, and there remember that your brother has something against you.”

Outward acts of worship are unacceptable to God as long as we harbor internal sin. They are particularly offensive if we retain a hateful attitude toward a brother or sister and yet attempt to come before God.
Worship is important for most religious people today. They can spend much time in places of worship, offering prayers, giving tithes, and doing all sorts of religious activities. But, as with the scribes and Pharisees, none of it is meaningful if carried out with the wrong attitude.
Presenting an offering at the altar was a familiar scene for Jesus’ listeners. On the Day of Atonement, for example, worshippers would bring animal sacrifices and give them to the priest as sin offerings. But that process must halt if the worshippers were to remember some hatred between themselves and someone else. Unresolved conflict has priority over external ceremony and must be settled.
Sin between us and other brothers & sisters must be resolved before we can bridge the gap of sin between us and God. The Lord told Israel, “What are your multiplied sacrifices to Me? . . . I have had enough of burnt offerings of Rams and the fat of fed cattle; and I take no pleasure in the blood of Bulls, lambs or goats. . . . Wash your selves, make yourselves clean; remove the evil of your deeds from My sight. Cease to do evil, learn to do good” (Isaiah 1:11, 16-17a).
Not to be at peace with someone else and yet to attempt to worship God is a hindrance to genuine fellowship.

Ask Yourself:
This is a call for worship to matter, and for relationship with God to be taken seriously. More than a Sunday morning verse, it’s a principle demanding conciliatory action in the days prior to the Lord’s day. Is there such a matter occurring in your life situation right now?
