Therefore, if you bring your gift to the altar, and there recall that your brother has anything against you, leave your gift there at the altar, go first and be reconciled with your brother, and then come and offer your gift. (Mt 5:20-26)

How important is reconciliation! In order to offer our gift to the Lord, we must first be reconciled with one another. Because otherwise, our gift smells to high heaven! We pray for Ukraine, we pray for peace.
