A SUMMONS TO RESOUNDING PRAISE.
Psalm 81:1-4.
PSALM 81:1. There may be a time for quiet contemplative worship, but this is not it. It is a time of loudness, a time of noise. It is a time of fulness of joy. We are not called to be perfect in our singing, but to “Sing aloud” and “make a joyful noise” nevertheless.
And no wonder, for we celebrate here “God our strength” who delivered His people out of Egypt, and sustained them in the wilderness (cf. Psalm 81:5-7, Psalm 81:10). We celebrate “the God of Jacob” who met us where we were, and brought us to where He wants us to be. We celebrate the God and Father of our Lord Jesus Christ, who delivered us out of the thraldom of sin and death, and into His heavenly Kingdom. We celebrate the God who has helped us hitherto (cf. 1 Samuel 7:12), and has promised to remain with us forever (cf. Hebrews 13:5).
PSALM 81:2. “Take a psalm.” Choose a ‘psalm, hymn or spiritual song’ (cf. Ephesians 5:19; Colossians 3:16). Take up the tambourine and bring in the stringed instruments (cf. Psalm 149:3; Psalm 150:4).
PSALM 81:3. “Blow up the trumpet.” This seems to refer to the shofar, the ram’s horn. There are two or three time markers in the verse: “the new moon”, “the time appointed”, and “our solemn feast day” (cf. Numbers 10:10). There are three compulsory feasts in ancient Israel’s calendar (cf. Deuteronomy 16:16), but perhaps the most significant blowing of the “trumpet” is that for the year of jubilee (cf. Leviticus 25:9).
Jesus pronounced Himself the fulfilment of the jubilee promise (cf. Luke 4:18-21). In a sense, the whole church age is the year of jubilee. And the end of that age will be punctuated with another trumpet call (cf. 1 Corinthians 15:52).
PSALM 81:4. “For this was a statute for Israel, and a law of the God of Jacob.” Christians may think to disqualify themselves from the worship of God because of the times when we have slipped back into the ways of our former selves: but the people of God as a whole are indicated under both their covenant name, “Israel”, and their pre-covenant name “Jacob”. We need not be presumptuous, but our Lord is ever ready to receive back the backslider.
