Im gonna try to correct some miss understandings about the use of the Psalms in addressing sin and the curse. I believe these Psalms are mainly confessions to be spoken in prayer and in meditation,,,quietly or as the conflict rises so they are spoken loud as if your fighting a war. There are some Psalms that are written to be shouted as the battle begins.
There are 7 penitent Psalms.In my speaking them for 40 years I find there is only one that teaches confession of sin in the orthodox way that we are taught. The other 6 are complaints about suffering physically and spiritually.
I understand the Psalms as teaching that there are no steps to God. There are pressing issues that we want addressed so we must see that in the beginning the Psalmist teaches us a universal principle that provides us with the confidence that God would listen to us according to our struggles and not according to our sin. Ps 5 7 But I, by your great mercy, will come into your house;in reverence will I bow down toward your holy temple." The Psalmist is teaching that we always approach God and enter because of His unfailing love. His unfailing love is the foundation of our petition and not our confession. His unfailing love can be expressed as His mercy , long suffering, gentle , kind, and forgiving. These words are all covenant promises that are the legal justification of being accepted in HIs presence. The whole covenant language of God is defined by His unfailing love. 6 4Turn, O LORD, and deliver me; save me because of your unfailing love.-{ covenant love}44 26 Rise up and help us; redeem us because of your unfailing love". Anyone who is familiar with praying the Psalms knows that Gods unfailing love creates the face to face history of a saint with God that is supported by the history of answered petitions. So its like starting with small battles that increase as we trust more in this face to face interaction.
Psalm 103 is a true teaching of the saints confession of sin. It is not a complaint or a curse. You see in these other Penitents there is a curse. 6 2 Be merciful to me, LORD , for I am faint;
O LORD , heal me, for my bones are in agony. 3 My soul is in anguish." Here he is complaining about a physical injury and his sin. But he curses those he blames. 10 All my enemies will be ashamed and dismayed; they will turn back in sudden disgrace. Again in38 3 Because of your wrath there is no health in my body;
my bones have no soundness because of my sin.4 My guilt has overwhelmed me like a burden too heavy to bear." he complains about a physical injury and his sin. But then he curses again.16 For I said, "Do not let them gloat or exalt themselves over me when my foot slips." Stop them so that i will not suffer. And you can see this in the other Penitent ones.103 1 Praise the LORD , O my soul;all my inmost being, praise his holy name.2 Praise the LORD , O my soul,and forget not all his benefits-
3 who forgives all your sins and heals all your diseases,
4 who redeems your life from the pit and crowns you with love and compassion, 5 who satisfies your desires with good things
so that your youth is renewed like the eagle's." This confession is totally directed at the Psalmist. There is no complaining or cursing. The Psalms teach that God does not count our sins. 12 as far as the east is from the west, so far has he removed our transgressions from us."In other words God does not require us to do certain steps to enter His presence. We confess freely because God has already taken care of our sin. Or we confess in order to present our petition in light of His unfailing love. This whole Psalm is a general teaching of the most exhaustive statements throughout the Psalms.
