Psa 18:4 The cords of death entangled me; the torrents of destruction overwhelmed me. 18:5 The cords of the grave coiled around me; the snares of death confronted me.
When we go through a trial we try to focus on the goal in getting through it. But the Psalmist is very careful in using his words. Now think of this for a second . If God has given us the solution in using the axioms do you think He knows the details of our troubles. Then why did God allow the Psalmist to describe them to Him? You will find that men are not like God because they do not like us to describe our troubles. They think we are complaining. But if God decreed the axioms did not He decree our ecperience? What happens if the Psalmist just described the solution and failed to describe God's creation of the trouble in His eternal counsel? He would fail in giving God the glory for decree in whatsoever comes to past. So the Psalmist is describing the words that created the trouble as coming from God in including it in the Psalms.  

When we observe the beautiful creation else get joy in describing it. But when we are suffering we do not think it too is God's creation. But the Psalmist describes the suffering to give glory to God and to use it by arguing that God is treating Zhim in anger like the wicked.   God loves to hear us describe our troubles.
