The second chapter of the book of Jonah is very much like a Psalm. It is the poetic record of Jonah's prayer while in the belly of the fish. The prayer is really a celebration of Jonah's deliverance from drowning in the sea (Jonah saw the fish as God's means of deliverance). In this prayer, Jonah reminds himself of several key aspects of God's character: God's mercy; God's sovereignty; God's grace; and God's power.
