In the depths of despair, the writer cried out to God. Despair makes us feel isolated and distant from God, but this is precisely when we need God most. Despair over sin should not lead to self-pity, causing us to think more about ourselves than God. Instead, it should lead to confession and then to God's mercy, forgiveness, and redemption. When we feel overwhelmed by a problem, feeling sorry for ourselves will only increase feelings of hopelessness; but crying out to God will turn our attention to the only one who can really help.
Psalms 130:3-4
Keeping a record of sins (or holding a grudge) is like building a wall between you and another person, and it is nearly impossible to talk openly while the wall is there. God doesn't keep a record of our sins; when he forgives, he forgives completely, tearing down any wall between us and him. Therefore, we fear (revere) God, yet we can talk to him about anything. When you pray, realize that God is holding nothing against you. His lines of communication are completely open.
