One of the great prayers of the Bible is in Daniel 9. Daniel offered it in response to reading Scripture. He understood what the Word said, and it affected him tremendously. He prayed, fasted, and confessed.
It is very short, toward the end, and really no more than one phrase--Then immediately Daniel returns to confession."turn away your anger and your wrath from Jerusalem, your city, your holy hill" (9:16).
Our prayers should be balanced. They should include worship, thanksgiving, requests and confession. It is not necessary that each prayer have all four, but as we examine our prayer life, all should be evident, including confession.
