When Phinehas the priest and the high officials heard this from the tribes of Reuben, Gad, and the half-tribe of Manasseh, they were satisfied. Phinehas son of Eleazar, the priest, replied to them, "Today we know the Lord is among us because you have not sinned against the Lord as we thought. Instead, you have rescued Israel from being destroyed by the Lord." (Joshua 22:30-31)(NLT)
Israel's three tribes that lived east of the Jordan river built an altar at the edge of the Promised Land, just west of the river. This altar was not intended to separate the tribes but rather to bear witness that all the tribes served the same God. Still, there was misunderstanding. So it is today. Sometimes misunderstandings over worship practices can cause God's people to become divided. Even when the Lord is genuinely worshiped by several groups, disputes can flare up. Let us follow Israel's wise example and recognize that the Lord accepts genuine worship from his people even though it may be different from other believers' worship.
O GOD, you delight in all who worship you with pure hearts. We confess that many times we have allowed differing styles of worship to divide your church. Purify our heart so that we might offer worship that pleases you. We thank you for the diversity of your people, which opens our eyes to a greater vision of you. Amen.
