Journey to Jerusalem Day 7

Psalm 51:1-6
1 Have mercy upon me, O God, in your great goodness; *
according to the multitude of your mercies
wipe away my offences.
2 Wash me thoroughly from my wickedness *
and cleanse me from my sin.
3 For I acknowledge my faults, *
and my sin is ever before me.
4 Against you only have I sinned, and done this evil in your sight, *
so that you are justified in your sentence, and blameless
in your judgment.
5 Behold, I was brought forth in wickedness, *
and in sin my mother conceived me.
6 But behold, you desire truth in the inward parts *
and shall make me understand wisdom secretly.

David's desire to be "washed" and "purged" from sin reflects from his conscience that he bears the mark (or stain) of corruption. A betrayal of God and man has occurred, as he had sent Uriah off to his death, the better for David to appropriate Bathsheba as a wife of his own.
After the passage of a year, David became conscious of the distance which he brought about between himself and God. David fears that separation is all the divine will see. Having been previously instructed in the divine wisdom as one close to God, he pleads for mercy on the basis of the covenantal loyalty, the loving kindness in which God holds his people.
The moral of the text can be succinctly recapitulated in St. Augustine's best-known quotation: "O Lord ... our heart is unquiet until it rests in you."
I love you, Jesus, my Love above all things.
I repent with my whole heart for ever having offended You.

Never permit me to separate myself from You again.
Grant that I may love You always.
Then do with me what you will. Amen.
--Alphonsus Liguori
