Psalm 100 is the last in a series of psalms that emphasize the LORD as King (93–100). It describes God’s people going into His house to worship Him, and it spells out what their attitude should be as they go. It also calls out to all the people of the earth, urging them to recognize that the LORD is God and inviting them to receive Him.

In a very practical sense, this psalm teaches us the actual purpose of the church: to joyfully express praise and thanksgiving to God, to present ourselves for God’s service, and to urge all people of the earth to come into a relationship with God through His Son.

A good example of praise is set forth for us by the prayer of an elderly saint of God at a prayer meeting one evening. He said,”O Lord, we will praise Thee; we will praise Thee with an instrument of ten strings!” People wondered what he meant, but understood when he continued, “We will praise Thee with our two eyes by looking only unto Thee. We will exalt Thee with our two ears by listening only to Thy voice. We will extol Thee with our two hands by working in Thy service. We will honor Thee with our own two feet by walking in the way of Thy statutes. We will magnify Thee with our tongue by bearing testimony to Thy loving kindness. We will worship Thee with our heart by loving only Thee. We thank Thee for this instrument, Lord; keep it in tune. Play upon it as Thou wilt and ring out the melodies of Thy grace! May its harmonies always express Thy glory!”
