Psalm 50 - This Psalm is the appointed one for this Sunday. Verse 1 is the key verse, “O Lord, make haste to help me.” This is the prayer of faith. When we reach out to the Savior with our burdens, joys, sorrows, and cares, He answers every petition. Our only request, “Thy will be done Lord, Thy will be done.”
Asaph was one of King David’s music leaders. Either Asaph wrote this psalm, or someone wrote it for him. Or perhaps someone wrote it long after his death, for singers that lived after him. The psalm is very much like Isaiah 1:11-20, and Micah 6:6-9. Isaiah and Micah wrote their books about 250 years after David and Asaph died. Psalms 73-83 are also psalms of Asaph.
The psalm is a picture of a Court of Law. This is a place where people decide whether someone has done right or wrong. If they have done wrong, the Court can send them to prison, or worse. In the psalm, Israel is in Court. God is telling them what they have done wrong. Everything in the sky and on earth must decide whether Israel has done right or wrong. God says that they have done wrong and that he will punish them if they do not obey him.
Now, read Exodus 20:2-17 and contemplate the difference between:
a) being safe at the Last Judgment because you have obeyed every rule,
b) being safe at the Last Judgment because you trust in the merits and work of Jesus Christ.
Collect for Psalm 50: Heavenly Father, because Jesus your servant became obedient to death, his sacrifice was greater than all the holocausts of old. Accept the sacrifice of praise we offer you through him, and help us show the effects of it in our lives by striving to do your will.
