Anyone who comes to the word and sacrament with an unreconciled heart stands judged by doing so.
In Jesus, service to the least brother or sister and service to God became one.
So when you are offering your gift at the altar, if you remember that your brother or sister has something against you, leave your gift there before the altar and go; first be reconciled to your brother and sister, and then come and offer your gift. Matthew 5:23-24
O guard my life, and deliver me; do not let me be put to shame, for I take refuge in you. May integrity and uprightness preserve me, for I wait for you. Psalm 25:20-21
