The Book of Psalms

Chapter 100: Serve the LORD with Gladness

Psalm 100 is the great psalm of thanksgiving, 'the Old Hundredth,' one of the best-loved calls to worship in all of Scripture. 'Make a joyful noise unto the LORD, all ye lands. Serve the LORD with gladness: come before his presence with singing.' It grounds worship in knowing the truth about God, '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,' and it shows us the road into His presence, 'Enter into his gates with thanksgiving, and into his courts with praise.' And it rests the whole of worship on the unchanging character of God: 'For the LORD is good; his mercy is everlasting; and his truth endureth to all generations.' The good, merciful, faithful God who made us and shepherds us is fully known in Jesus Christ, in whom we serve with gladness and enter with thanksgiving.

With Gladness

Serve the LORD with Gladness (Psalm 100:1-2)

A worldwide call to glad, singing worship.

Psalm 100:1-2

Make a Joyful Noise unto the LORD

"A Psalm of praise. Make a joyful noise unto the LORD, all ye lands. Serve the LORD with gladness: come before his presence with singing."

Word Study

"A Psalm of praise," Hebrew mizmor letodah (מִזְמוֹר לְתוֹדָה), a psalm for thanksgiving. The title sets the key before a single line is sung. This is a psalm for thanksgiving, and the same word for thanksgiving returns at the end, where we are told to "enter into his gates with thanksgiving."

"make a joyful noise," hari'u (הָרִיעוּ), raise a ringing shout. The opening call is not for a murmur but for a shout. Worship here is loud and unashamed, the right response of a creature to its Maker.

"all ye lands," kol-ha'aretz (כָּל־הָאָרֶץ). Mark the reach of the summons. This is no private hymn for one people; it flings the call to joyful service across the whole earth.

"serve," ivdu (עִבְדוּ). Worship here is not only song but service, the work owed by a servant to his Lord. The psalm sets this word in the imperative alongside "come," so that our labour and our singing belong to the same act.

"with gladness," besimchah (בְּשִׂמְחָה). Gladness is here commanded, set in the imperative alongside "serve." The psalm treats gladness as part of the worship God is owed, a thing we are called to bring, not merely to feel; He does not want grudging servants.

"with singing," birnanah (בִּרְנָנָה). We are to "come before his presence with singing." He is worthy of worship that sings rather than sighs, and the psalm will not let us settle for anything colder.

Explanation

The heart of this opening is a small phrase we too easily read past: "Serve the LORD with gladness." Notice that gladness is here commanded, set in the imperative alongside "serve" and "come." That should stop us. We tend to think of joy as a mood that comes and goes, something we cannot help; but the psalm treats gladness as part of the worship God is owed, a thing we are called to bring, not merely to feel. And behind the command lies a truth about the God we serve: He does not want grudging servants. Service rendered with a long face, out of grim duty, dishonours Him, as if He were a hard master to be endured. He is worthy of glad service, of a heart that delights to obey, of worship that sings rather than sighs. This does not mean we manufacture false cheer; it means we remember who God is until the gladness is real, for the God we serve is good, and to know Him truly is to be glad in Him. And mark the reach of the summons, "all ye lands." This is no private hymn for one people; it flings the call to joyful service across the whole earth. The right response of every creature to its Maker is glad, singing worship, and the psalm will not let us settle for anything colder.

Gospel Focus

"Serve the LORD with gladness", this glad service is exactly what the Lord Jesus Christ makes possible, for He says, "my yoke is easy, and my burden is light" (Matthew 11:30), and in Him "his commandments are not grievous" (1 John 5:3). The service the gospel calls for is not the cringing toil of a slave but the glad obedience of a child, done "as the servants of Christ, doing the will of God from the heart" (Ephesians 6:6). What makes the difference is love: we serve gladly because we have been loved greatly, redeemed at the cross, adopted as sons, given the joy of the Lord as our strength. So if your service to God has grown heavy and joyless, the answer is not to try harder to feel happy, but to return to Christ and remember His goodness until gladness rises again. He is worth serving, and worth serving with a whole and singing heart.

Know Ye

It Is He That Hath Made Us (Psalm 100:3)

Worship grounded in knowing that we are made, not self-made.

Psalm 100:3

Know Ye That the LORD He Is God

"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."

Word Study

"know ye," Hebrew de'u (דְּעוּ). At the center of this psalm of feeling stands a command to think. True worship is never mere emotion whipped up in a vacuum; it rests on knowing the truth about God, and the more we know Him, the more rightly we praise.

"the LORD he is God," YHWH hu Elohim (יְהוָה הוּא אֱלֹהִים). This is the content of the knowledge commanded: the covenant LORD, and no other, is God. Everything the psalm asks of us rests on this single confession.

"it is he that hath made us," hu asanu (הוּא עָשָׂנוּ). We are creatures. We did not bring ourselves into being, we do not sustain our own breath, we owe every heartbeat to Another.

"and not we ourselves," velo anachnu (וְלֹא אֲנַחְנוּ). The pointed denial strikes directly at the oldest and proudest lie of the human heart, that we are self-made, self-owned, answerable to no one. That single confession dethrones all our self-sufficiency and puts us in our right place before God.

"the sheep of his pasture," tzon mar'ito (צֹאן מַרְעִיתוֹ). The verse does not leave us as mere creatures under a distant Maker; it adds the tenderest word. We belong to Him twice over, made by His hand and shepherded by His care.

Explanation

At the center of this psalm of feeling stands a command to think: "Know ye that the LORD he is God." True worship is never mere emotion whipped up in a vacuum; it rests on knowing the truth about God, and the more we know Him, the more rightly we praise. And the particular truth the psalm fixes on is this: "it is he that hath made us, and not we ourselves." Two things are packed into that phrase. First, we are creatures, we did not bring ourselves into being, we do not sustain our own breath, we owe every heartbeat to Another. And second, the pointed denial, "not we ourselves", strikes directly at the oldest and proudest lie of the human heart, that we are self-made, self-owned, answerable to no one. The modern world says a person is whatever he makes himself; the psalm says, No, you did not make yourself; God made you, and you are His. That single confession dethrones all our self-sufficiency and puts us in our right place before God. But the verse does not leave us as mere creatures under a distant Maker; it adds the tenderest word: "we are his people, and the sheep of his pasture." We belong to Him twice over, made by His hand and shepherded by His care. To know that the LORD is God, that He made us and keeps us as a shepherd keeps his flock, is the solid ground on which all glad worship stands.

Gospel Focus

"It is he that hath made us", the Maker of this verse is the Lord Jesus Christ, for "all things were made by him; and without him was not any thing made that was made" (John 1:3). And in the gospel He makes us a second time, for "we are his workmanship, created in Christ Jesus unto good works" (Ephesians 2:10), fashioned once in creation and again in the new birth. To "know that the LORD he is God" is the very heart of eternal life, which Jesus defined as this: "that they might know thee the only true God, and Jesus Christ, whom thou hast sent" (John 17:3). And "the sheep of his pasture" are the flock of the Good Shepherd, who says, "I am the good shepherd, and know my sheep" (John 10:14), and who laid down His life for them. So do not think of yourself as self-made or self-owned. You were made by Christ, and if you are His, made anew in Him, and you are a sheep of His pasture, held in the hand of the Shepherd who died for you. Know this, and worship.

Enter with Thanksgiving

For the LORD Is Good (Psalm 100:4-5)

The road into God's presence, and the changeless character that welcomes us there.

Psalm 100:4-5

His Mercy Is Everlasting

"Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name. For the LORD is good; his mercy is everlasting; and his truth endureth to all generations."

Word Study

"enter into his gates," Hebrew bo'u she'arav (בֹּאוּ שְׁעָרָיו). The psalm now tells us how to come to God. There is a way in, and the worshipper is commanded to take it rather than to hang back outside.

"with thanksgiving," betodah (בְּתוֹדָה). The road into God's presence runs through gratitude. You do not come stomping into His courts with complaints, or sidling in with demands; you come giving thanks. It is the same word that titles the whole psalm.

"his courts," chatzerotav (חֲצֵרֹתָיו). Thanksgiving is the gate; praise is the courtyard. Having entered, the worshipper goes on blessing His name, so that the whole approach to God is paved with gladness for what He has already done.

"the LORD is good," tov YHWH (טוֹב יְהוָה). Here is the first of three great constants that ground all this worship. Goodness is His very nature, not a mood but His settled character.

"his mercy is everlasting," le'olam chasdo (לְעוֹלָם חַסְדּוֹ). The second constant. His mercy never runs dry, never reaches its last drop, never expires.

"his truth endureth," ad-dor vador emunato (עַד־דֹּר וָדֹר אֱמוּנָתוֹ), his faithfulness to all generations. The third constant. His faithfulness does not weaken with time or fail from one age to the next. Our worship is anchored not to our own shifting feelings but to a character that never moves.

Explanation

These closing verses tell us how to come to God and why we can. First, the how: "Enter into his gates with thanksgiving, and into his courts with praise." The road into God's presence runs through gratitude. You do not come stomping into His courts with complaints, or sidling in with demands; you come giving thanks, blessing His name. Thanksgiving is the gate; praise is the courtyard; the approach to God is paved with gladness for what He has already done. Second, and most important, the why, the ground on which all this worship rests, stated in three great constants of God's character: "For the LORD is good; his mercy is everlasting; and his truth endureth to all generations." Look at how each is unbreakable. He is good, that is His very nature, not a mood but His settled character. His mercy is everlasting, it never runs dry, never reaches its last drop, never expires. His truth, His faithfulness, endureth to all generations, it does not weaken with time or fail from one age to the next. Notice that our worship is not anchored to our own shifting feelings, which rise and fall, but to God's changeless character, which never moves. That is why the psalm can command gladness: because the God we praise is always good, always merciful, always faithful. Whatever the day holds, these three never change, and so there is always ground for thanksgiving, always reason to enter His gates with praise.

Gospel Focus

"Enter into his gates with thanksgiving", the way into God's presence is opened fully in Jesus Christ, for "through him we both have access by one Spirit unto the Father" (Ephesians 2:18), and we now have "boldness to enter into the holiest by the blood of Jesus" (Hebrews 10:19). The gate that thanksgiving approaches is, in the end, Christ Himself, who said, "I am the door." And the three unchanging grounds of worship are all secured in Him. That "the LORD is good" is proved above all at the cross, where "the goodness of God leadeth thee to repentance" (Romans 2:4). That "his mercy is everlasting" is sealed in the everlasting salvation Christ has won. And that "his truth endureth to all generations" is guaranteed in Him, for "all the promises of God in him are yea, and in him Amen" (2 Corinthians 1:20). So enter God's gates through Christ, with thanksgiving in your heart, resting not on your changing feelings but on the good, merciful, faithful character of God, unchanged and unchangeable in Jesus Christ.

Psalm in Review

Psalm 100, the beloved Old Hundredth, is the classic call to joyful, thankful worship. It summons "all ye lands" to "make a joyful noise unto the LORD" and to "serve the LORD with gladness," treating joy not as a passing mood but as part of the worship God is owed. It grounds that worship in knowing the truth: "Know ye that the LORD he is God: it is he that hath made us, and not we ourselves," a confession that dethrones our self-sufficiency and puts us in our place as creatures made and shepherded by God, "the sheep of his pasture." It shows the road into His presence, "Enter into his gates with thanksgiving, and into his courts with praise," and rests the whole of worship on the three changeless constants of God's character: "the LORD is good; his mercy is everlasting; and his truth endureth to all generations." All of it is fulfilled in Jesus Christ, who makes glad service possible, who made us and makes us new, who opens the gate into God's presence by His blood, and in whom the goodness, mercy, and faithfulness of God are sealed for ever. Psalm 100 teaches us to serve God gladly, to know we are His, and to enter His gates with thanksgiving.
