Psalm 130 Mar. 15 A Song of Ascents.  1Out of the depths I have cried to You, Yahweh. 2Lord, hear my voice. Let Your ears be attentive to the voice of my petitions. 3If You, Yah, kept a record of sins, Lord, who could stand? 4But there is forgiveness with You, therefore You are feared. 5I wait for Yahweh. My soul waits. I hope in His word. 6My soul longs for the Lord more than watchmen long for the morning; more than watchmen for the morning. 7Israel, hope in Yahweh, for with Yahweh there is grace, with Him is abundant redemption. 8He will redeem Israel from all their sins.   

Commentary

130:3 God doesn’t keep a record or legal list of sins in the sense that He doesn’t hold them against us; it’s not that He as it were erases those parts of His ‘memory’, for His word is full of the memory of human sin which He has forgiven. The LXX is applied to each of us in 1 Cor. 13:5- we too are not to keep a record of others’ wrongs against us. God’s forgiveness of us is to be the template for our forgiveness of others. It’s not possible to forget them, in the sense that we have no power over our brain’s mechanism of forgetting; but we can forgive them in the sense that we do not count them any longer against the person.
