Psalm 81:1-3 Sing aloud unto God our strength: make a joyful noise unto the God of Jacob. Take a psalm, and bring neither the timbrel, the pleasant harp with the psaltery. Blow up the trumpet in the new moon, in the time appointed, on the solemn feast day.
God’s people are commanded and expected to worship God exuberantly and praise God extravagantly in response to His awesome power and great love shown unto us. When it is time for music and praise, whether monthly or weekly in the assembly, or daily in private, we pull out all the stops. We sing loudly and joyfully. We use the musical instruments we have: psalm, timbrel, harp, psaltery (lyre), and trumpet. In our day we may use organ, piano, guitar, drums, etc., along with voice. Nothing is too loud or boisterous for God, for He is worthy.
There is a worship life and a life of worship, in which we are “making melody in our heart to the Lord.” Our daily life of constant worship is punctuated with regular public, joint expressions of praise in the great congregation. Exuberance is the believer’s appropriate and normal response to the extravagant love God has shared with us in the person and work of His Son. We are so overwhelmed with love and overcome by the Gospel that we sing aloud.
