Dear brothers and sisters in Christ,
A Psalm of David.
15:1 O Lord, who shall sojourn in your tent?
Who shall dwell on your holy hill?
2 He who walks blamelessly and does what is right
and speaks truth in his heart;
3 who does not slander with his tongue and does no evil to his neighbor,
nor takes up a reproach against his friend;
4 in whose eyes a vile person is despised,but who honors those who fear the Lord;
who swears to his own hurt and does not change;
5 who does not put out his money at interest and does not take a bribe against the innocent.
He who does these things shall never be moved.
From The Lutheran Study Bible:
Sincerity and the righteous treatment of others, as taught in the Ten Commandments, are emphasized as the foundation to genuine worship. Sad to say, there are times that we come to worship God in an unworthy manner. E.g., we may remain unreconciled with others or persist in behaviors we know to be wrong. As God's true template and the mercy seat where full forgiveness is freely given, our Lord Jesus Christ still calls us unto Himself. Through His grace, we are made right with God and counted worthy to stand before the Father's throne.
In other words: the only person worthy of sojourning in God's holy tent, and dwelling on His holy hill, is He who knew no sin--Jesus Christ. Yet, because he became sin, know we who are baptized into Him have become the righteousness of God. He takes the punishment that we deserve, and gives to us the rewards that He has earned through his perfect obedience.
And so we pray:
Almighty God, grant that all our worship and life may be acceptable in Your sight; through Jesus Christ, our Lord. Amen.
