"For the LORD is good; His mercy is everlasting; and His truth endureth to all generations" (Psalm 100:5).
Psalm 100 is entitled, "A Psalm of praise." Like Psalm 23, it is one of the most familiar and beloved of the one hundred and fifty psalms.
In it the psalmist's great desire is that all the peoples of the earth would recognize the true "LORD," and out of a heart of heartfelt gratitude, praise and serve Him (vv. 1-2). The author, David, assures us that this Lord is the only true God and Creator of us all. "It is He that hath made us, and not we ourselves" (v. 3).
Therefore, we are to acknowledge His Lordship by willingly worshipping Him with thanksgiving and praise, blessing His name (v. 4).
The complete fulfillment of this psalm is believed by many to be in the millennium, the one thousand year reign of Christ, when "the earth shall be full of the knowledge of the LORD, as the waters cover the sea" (Isaiah 11:9). It will be at that time that "all ye lands" will "Make a joyful noise unto the LORD" (v. 1).
Believers in this present age of grace do not have to wait to do all that this psalm enjoins. They have the privilege to sing, praise, worship, and be thankful on a daily basis, blessing God for who He is and what He has done.
David ends Psalm 100 extolling three great attributes of God.
1. "The LORD is good" (v. 5). "Oh how great is thy goodness, which thou hast laid up for them that fear thee" (Psalm 31:19).
2. "His mercy is everlasting" (v. 5). "But the mercy of the LORD is from everlasting to everlasting upon them that fear Him" (Psalm 103:17).
3. "His truth endureth to all generations" (v. 5). NPS
