Summer in the Psalms | Psalm 100

The sermon opens with a familiar scene: a child receives a gift and enjoys it without a word of thanks, until a parent prompts, "What do you say?" The preacher applies this to all of us—we readily enjoy God's blessings, depend on His provision, and receive His daily mercies, yet we often forget to thank the Giver. Psalm 100 is God's loving reminder to His children: "What do you say?" The psalm teaches three essential truths about giving thanks.

1. Show You Are Thankful (vv. 1–2)

SHOUT — Show gratitude through joyful praise: "Make a joyful noise to the LORD" (Psalm 100:1).

SERVE — Show gratitude through glad service: "Serve the LORD with gladness!" (v. 2).

SING — Show gratitude through joyful singing: "Come into his presence with singing!" (v. 2).

Thanksgiving is not merely a feeling; it is demonstrated through praise, service, and song.

2. Know Whom You Are Thanking (v. 3)

Know that He alone is God — "Know that the LORD, he is God!"

Know that He created us — "It is he who made us."

Know that we belong to Him — "And we are his; we are his people."

Know that He shepherds us — "We are... the sheep of his pasture."

Our thanks is directed to a specific Person: the Lord—our Creator, our Owner, and our Shepherd.

3. Go to Give Thanks (vv. 4–5)

Go intentionally — enter His gates with thanksgiving (v. 4).

Go together — enter "his courts with praise" as His people (v. 4).

Go thankfully — "Give thanks to him; bless his name!" (v. 4).

Go because the Lord is good — "For the LORD is good" (v. 5).

Go because His love endures — "His steadfast love endures forever" (v. 5).

Go because His faithfulness continues — "His faithfulness to all generations" (v. 5).

Know, Show, Go—so that the nations and all generations may come and worship the Lord. The sermon closes with the call to observe the Lord's Supper (1 Corinthians 11:23–26), a fitting act of thankful remembrance of Christ, the greatest Gift of all—the One who gave Himself for our salvation (2 Corinthians 9:15).
