Psalm 4:1 Answer me when I call, O God of my righteousness! You have given me relief when I was in distress. Be gracious to me and hear my prayer!
2 O men, how long shall my honor be turned into shame?
How long will you love vain words and seek after lies? Selah
3 But know that the Lord has set apart the godly for himself;
the Lord hears when I call to him.
4 Be angry, and do not sin; ponder in your own hearts on your beds, and be silent. Selah
5 Offer right sacrifices, and put your trust in the Lord.
6 There are many who say, “Who will show us some good?”
Lift up the light of your face upon us, O Lord!
7 You have put more joy in my heart
than they have when their grain and wine abound.
8 In peace I will both lie down and sleep;
for you alone, O Lord, make me dwell in safety.
Intended as an evening prayer, Psalm 4 begins and ends with the request for and confession of confidence in the Lord’s presence and protection. It is God’s proven faithfulness in the past (Ps. 3) and the certainty of his covenant righteousness for the future that permit the psalmist — the Davidic King — to lie down in peace.
In contrast with the “many” who (once again) seek after vanity and lies (Cf. Ps. 1:2, because in such things they find their delight rather than in God’s Word), the King responds with the promise and truth of God’s election and favor (2:6), on the basis of which he knows that God will always hear and answer his prayer. As in Psalm 1, loving vanity and seeking lies will ultimately prove self-destructive. Those who delight in such things “have forsaken [the Lord], the fountain of living waters” and have “hewn out for themselves broken cisterns that can hold no water” (Jer. 2:13). Yet they wonder why they can find no good thing. Is this not sheer absurdity?
In reality, as the King attests, there is no good apart from the Lord and the light of his face. Even the greatest pleasures that the world can offer — here represented by the finest wine and the richest food — are loss and rubbish compared with the surpassing joy of knowing the King Jesus (Phil. 3:8). Yet we come to know this only when illuminated by the light of the face of Christ, for it is in his face, and his face alone, that we behold “light of the knowledge of the glory of God” (2 Cor. 4:6) that causes all else to appear as mere shadow.
Thus, it is the Lord Jesus Christ “alone” who is everything that we need. He is our joy, he is our peace, he is our rest, he is our safety.
