Psalm Devotional
Open Your Mouth Wide!
The two great intentions of our religious assemblies,” writes Matthew Henry, “are to give glory to God and to receive instruction from God…we do not go to church to sleep nor to be idle” (commentary on Psalm 81). Public worship is designed by the Lord as the primary means of grace in which He intends us “to behold the beauty of the Lord and to inquire in His temple” (Ps. 27:4). These are the two great themes addressed in Psalm 81.
The setting of the psalm is clearly one of the feast days of Old Testament worship. The form is of an appeal by God to His people to be serious about giving Him the glory and receiving and living His revealed Word and will. Anything less is a hypocritical sham that spits in the face of God. Worship is holy work.
God’s first question is: “Will you give Me the glory as you come together to worship?” (vv. 1-7). What does it mean to give Him the glory?
