God promises great blessings to his people, but many of these blessings require our active participation. He will set us free from our fears (34:4, 6), guard and rescue us (34:7), show us goodness (34:8), supply our needs (34:9), listen when we call to him (34:15), and redeem us (34:22), but we must do our part. We can appropriate his blessings when we seek him (34:4, 10); cry out to him (34:6, 17); trust him (34:8); fear him (34:7); reverence him (34:9); refrain from lying (34:13); turn from evil, do good and seek peace (34:14); are brokenhearted (34:18); and serve him (34:22).

1 Of David. When he pretended to be insane before Abimelech, who drove him away, and he left. I will extol the LORD at all times; his praise will always be on my lips.
2 My soul will boast in the LORD; let the afflicted hear and rejoice.
3 Glorify the LORD with me; let us exalt his name together.
4 I sought the LORD, and he answered me; he delivered me from all my fears.
5 Those who look to him are radiant; their faces are never covered with shame.
6 This poor man called, and the LORD heard him; he saved him out of all his troubles.
7 The angel of the LORD encamps around those who fear him, and he delivers them.
8 Taste and see that the LORD is good; blessed is the man who takes refuge in him.
9 Fear the LORD, you his saints, for those who fear him lack nothing.
10 The lions may grow weak and hungry, but those who seek the LORD lack no good thing.
11 Come, my children, listen to me; I will teach you the fear of the LORD.
12 Whoever of you loves life and desires to see many good days,
13 keep your tongue from evil and your lips from speaking lies.
14 Turn from evil and do good; seek peace and pursue it.
15 The eyes of the LORD are on the righteous and his ears are attentive to their cry;
16 the face of the LORD is against those who do evil, to cut off the memory of them from the earth.
17 The righteous cry out, and the LORD hears them; he delivers them from all their troubles.
18 The LORD is close to the brokenhearted and saves those who are crushed in spirit.
19 A righteous man may have many troubles, but the LORD delivers him from them all;
20 he protects all his bones, not one of them will be broken.
21 Evil will slay the wicked; the foes of the righteous will be condemned.
22. The LORD redeems his servants; no one will be condemned who takes refuge in him.
