Praying when at a low ebb

The probable setting: run-up to Absalom's rebellion - David aware of some conspiracy, but the awareness of his sins, the machinations of his enemies, and a measure of sickness prevent him from taking matters in hand.

1. The beatitude v1-3
2. The troubles v4-9. David's sense of sin and his enemies.
3. The reliable covenant God v10-13
4. Our sympathetic high priest v9; prophecy concerning Christ, his faithfulness and ability to succour his people. Psalm 55:22.
