If worry keeps you from getting a good night’s sleep, Psalms 3 and 4 are what you need. Both psalms were probably written when David was exiled from Jerusalem because his son Absalom had stolen the kingdom (2 Sam. 15–18). Psalm 3 is a morning psalm (v. 5), and Psalm 4 is an evening psalm (v. 8).
How was David able to sleep when he was in such danger? The enemy was against him (vv. 1, 6) but David knew that God was for him. God surrounds you (v. 3), sustains you (v. 5), and saves you (v. 7). When people discourage you (v. 2), God lifts up your head and keeps you going (v. 3).
God never sleeps (Ps. 121:3–4), so why should you stay awake and worry?
“If you can’t sleep, don’t count sheep—talk to the Shepherd!”
