Address and Petition v.1-2
In verses 1 and 2 the author is crying out to and addressing God. He is petitioning God to vindicate him and save him from the problem. He is calling God to listen and through doing this petition is reminding himself that it is only God who can deliver and it is only God who can save him. This is truth that we must remind ourselves of daily. It is only God who can save us and deliver us from evil.
The author then moves in verse 3 to his complaint. As I will tell my congregation on Sunday, a true complaint is just an expression of grief, pain, or dissatisfaction. So the question would be, why do we not express this to God, the one and only who can actually deal with it. Why do we complain to others or get angry at God, when as this Psalm shows us we just need to petition God and tell Him why and how it hurts.
Trust v. 4-5
Yes, life hurts, the psalmist would say. Yes, life is unfair. Yes, as Jesus said, when we love Him the world will persecute and ridicule us. But none of that should ever shake our trust in a good God. The author of this lament makes sure to trust God, in spite of all that is happening to him and is frustrating him. God is our help, he is the only one who can and will sustain us. We just need to trust in Him.
Praise of coming deliverance v.6-7
The author ends his song with a praise for the fact that God will be his deliverer. He reminds his hearers that God has delivered in the past and that in His goodness, he will deliver again from this new frustration and anxiety. This is an important Biblical truth for us also. God has saved us in the past, both by the cross and daily provisions. This recognition should then spurn us on to future faith in God. God is a faithful God. We can rest in the brokenness. Resting in the fact that the same faithful God yesterday will be with us tomorrow.
