Psalm 100, so many riches and guidance in five short verses. God’s love is “Steadfast and Endures Forever.”
Psalm 100:1-2, “1 A Psalm of praise. Make a joyful noise unto the LORD, all ye lands. 2 Serve the LORD with gladness: come before his presence with singing.”
Here is a call to praise and worship.
Psalm 100:3, “Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture.”
John 10:4-5, “4 And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. 5 And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.”
Our God is the Creator God, our shepherd and worthy of worship.
Psalm 100:4, “Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name.”
Again, a call to worship and perhaps a foretelling of Matthew 28:18-20 and the Great Commission.
Psalm 100:5, “For the LORD is good; his mercy is everlasting (H5769); and his truth endureth to all generations.”
H576, everlasting, the vanishing point; generally, time out of mind (past or future), eternity; always, perpetual, at any time, beginning of the world without end.
Many generation later Jesus made His Triumphal Entry into Jerusalem as the Angel Gabriel shared with Daniel hundreds of years earlier [Daniel 9:25]; in fulfillment of Zechariah 9:9, “Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.”
As Jesus entered Jerusalem people were rejoicing greatly, Luke 19:38, “Saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest.” This did not set well with the Pharisees who said, “Master, rebuke thy disciples.” Luke 19:40, “And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.”
Matthew 28:18-20, “18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen,” the Great Commission.
More to the point is this commentary, “We learn from these five short verses that worship is simple. The longest words are thanksgiving, everlasting, and generations. The language is neither involved nor flowery. We learn too that the simple recital of facts about God is worship. The words themselves carry cargoes of wonder. The plain facts are more wonderful than fiction.”
