Third, know that “we are his” (Ps. 100:3). He owns us by virtue of creation. He has a right to our service, our thanksgiving, our loyalty. He has enlivened us. He has directed us by His will. He has formed us for His glory (Isa. 43:7). And, while His creation right over us demands our devotion, His saving mercies all the more so! We are not our own. We have been bought with a price (1 Cor. 6:19–20). Precious blood has been spilled, better blood than bulls and goats, the blood of His beloved Son. We come to serve with gladness as those freed from our sins by Jesus’ blood and made a kingdom and priests to God (Rev. 1:5–6).
Fourth, know that “we are his people” (Ps. 100:3). Our God is our ruler, and we have been designated by grace as His subjects. He is our King, our Judge, our Lawgiver. We are citizens of His kingdom bound to follow His directions for life. Moreover, He’s identified Himself with us. The great covenant declaration throughout the Scripture is “I will be your God, and you will be my people” (Gen. 17:7; Ex. 6:7; Lev. 26:12; Ezek. 36:28; Rev. 21:7). We’ve been drawn into a covenantal relationship, one filled with lavish grace. We are “a chosen race, a royal priesthood, a holy nation, a people for his own possession” that we may proclaim his excellencies (1 Peter 2:9).
Fifth, know that we are “the sheep of His pasture” (Ps. 100:3). In choosing us, drawing us to Himself with cords of steadfast love, the Lord has stooped to take us under His tender care. It is not simply that He has made us and functions as our King. He is our Shepherd. He carries us near to His heart, gently leading the weak (Isa. 40:11). We are the objects of special affection, and He gives us all kinds of good things to enjoy. He feeds us, nourishes us, and protects us, and that protection will go beyond our farthest comprehension when the Good Shepherd lays down His life for the sheep (John 10:11). We are precious to the Lord, a crown of beauty, a royal diadem (Isa. 62:3), and as the Lover of our souls, He has given us refuge under the shadow of His wings (Ps. 17:8).
Sixth, after giving more commands to enter His gates, to give thanks and bless Him (Ps. 100:4), the psalmist says we should do so “for the Lord is good” (Ps. 100:5). Who can begin to describe the goodness of the Lord? He is good in Himself—namely, He’s kind (Titus 3:4), tender-hearted (Ps. 34:18), full of compassion (Ex. 34:6), boundless in mercy (Ps. 25:6; Eph. 2:4), lavishing grace (Eph. 1:8), and great in love (Eph. 2:4). This is who He is, and goodness is likewise what He does, as seen in Psalm 119:68: “You are good and do good.” The goodness of God’s works are seen in creation, providence, and redemption, and a sight His mercy over all He has made (Ps. 145:9), should compel believers to bless Him.
Seventh, a particular evidence of His goodness is that “his steadfast love endures forever” (Ps. 100:5). The Lord Himself is the fountain of living waters, and therefore all He is as a God of steadfast love can never run dry. His covenant loyalty, His dogged affection, can never wear out. His love is from everlasting to everlasting on those who fear Him (Ps. 103:17). Even when hard providences come, when our hearts are heavy with grief, when the fiercest afflictions strike, still His steadfast love is new every morning (Lam. 3:22–23). How can that fact fail to fire your soul for worship?
Finally, in connection to His steadfast love, “his faithfulness [endures] to all generations” (Ps. 100:5). Not one word of all His good words will fall to the ground (Josh. 21:45; 23:14; 1 Kings 8:56). While everything we experience in this life fails us—flowers fade, offers expire, contracts run out, men prove unreliable—the Lord’s Word stands forever (Isa. 40:8). He will not renege on a promise. He is trustworthy. Therefore, when we come to worship, even if the darkness of a cursed world aims to pull us into despair, we have a future and hope, and these things resting on God’s faithful promise can never wear out. Oh, what gladness should erupt from our hearts! If we would give our Lord the thanks owed to Him, let us prime the pump of our heart with these truths from Psalm 100. Let us ready ourselves to resound with praise to our great God.
