“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.”
(Psalm 100:3)
The history of redemption is the history of God’s unwavering commitment to His people. From the beginning, Scripture testifies to the reality that the Lord is not only Creator but also Covenant Keeper. He has bound Himself in mercy to the work of His hands, declaring through His covenants that His steadfast love will not fail.
The covenant of works established with Adam set forth the condition of life and blessing tied to obedience. In this covenant, man was reminded that all good flowed from the hand of God, but also that failure to obey would bring death. Adam’s fall shattered that first covenant, leaving humanity condemned and helpless. This introduced a gulf no human effort could bridge, revealing the desperate need for divine intervention.[1]
That intervention came through the covenant of grace, established in Christ. Unlike the covenant of works, this covenant is grounded not in man’s performance but in God’s mercy. It is sometimes called the covenant of faith, for it promises life and salvation to all who believe in the finished work of Christ. In this covenant, God not only reconciles sinners to Himself but also transforms their hearts, granting the Holy Spirit to dwell within them. By His Spirit, He enables what fallen man could never achieve in his own strength—obedience flowing from faith and love.
The covenant has been administered in different forms across redemptive history, yet the substance remains constant. Under the Old Testament, the administration came through promises, sacrifices, prophecies, and ceremonies, all pointing forward to Christ. These shadows instructed the people of God, preparing their hearts to trust in the Savior who was to come. Every altar, every priest, every sacrifice was a signpost to the true Lamb who would take away the sin of the world.
With the coming of Christ, the covenant reached its fullness. What was once shadow became substance, promise became performance. Now, in the New Testament era, the covenant is administered more simply yet with greater clarity and power. The preaching of the Word and the sacraments of Baptism and the Lord’s Supper convey with full spiritual efficacy the grace of Christ to all who believe. No longer veiled, the gospel shines plainly: salvation is by grace alone through faith alone in Christ alone.
This covenant of grace, in every age, displays the constancy of God’s redemptive plan. It is a plan not bound by culture or time but reaching across the whole of history to gather a people for Himself. Psalm 100:3 assures believers that the Lord who made them also claims them: “we are his people, and the sheep of his pasture.” The Shepherd will not forsake His flock.
Here lies the certainty for every Christian soul: God’s commitment to His people is unshaken. He who called them will keep them. He who began a good work will finish it. The covenant of grace guarantees that the sheep of His pasture will dwell safely under His care forever.
Contemplations:
- The unchanging promise. Psalm 100:3 reminds me of the immutable, timeless nature of God’s various covenants under both law and grace which demonstrate His unwavering commitment to His people. It comforts me to know that despite the different ways in which God’s covenants have been administered, the essential thread running through them all remains the same—the promise of salvation and eternal life in Christ.
- The grace of belief. The covenant of grace promises life and salvation through faith in Christ simply by believing in the finished work of Christ. As Paul states in Ephesians 2:8, it is not “of ourselves” that we are saved, for it is a “gift of God.” Further, this grace does not simply guarantee passage to heaven, it also invites us into a transformed life here and now, one that is empowered by the Holy Spirit to live in a way that honors God.
- From shadows to substance. The transition from the Old to the New Testament highlights a movement from shadow to substance, from types and ordinances to their fulfillment in Christ (from promise to performance). It is a fascinating study to see how the rituals and ceremonies of the Old Testament, which once seemed like mere religious practices, find their meaning and fulfillment in Jesus. This realization deepens my appreciation for the Bible as a unified story of redemption.
- A universal call. Above all, the covenant of grace that extends to all people reflects God’s transcendent love. Under this New Covenant, the gospel is not confined to a specific people or time but is a universal call to humanity, confirming that the mission of the church is to share the love, work and merit of Christ with everyone, regardless of their background or beliefs.
Prayer (supplication):
O Lord, covenant-keeping God, Shepherd of Your flock, I bow before You in awe of Your faithfulness. You are the One who has made me and not I myself. I belong to You, the sheep of Your pasture, and I cry out for Your sustaining grace. Anchor me in the certainty of Your covenant love. Keep me from wandering into self-reliance or doubting Your promises. Strengthen my faith that I may rest in the truth that You who began the good work will bring it to completion.
Father, I plead with You to deepen my trust in the covenant of grace. Too often I forget that my standing before You is not by my works but by Christ alone. Guard me from pride that leans on self, and from despair that doubts Your mercy. Let me hold fast to the truth that salvation is Your gift, freely given, secured in the blood of Your Son.
Grant me, Lord, the strength to live daily in the power of this covenant. Let my faith be active, my obedience sincere, my devotion undivided. Fill me with Your Spirit that I may walk worthy of the calling with which I have been called. Let Your Word dwell richly in me, shaping my thoughts, desires, and actions. Where shadows once stood, let me see clearly the substance of Christ, and may His glory draw me ever closer.
O God of steadfast love, extend the call of Your covenant through me. Use my lips to proclaim Christ to the lost, my hands to serve in His name, my heart to love as He has loved. Make me an instrument of Your grace in a world darkened by sin. Keep me from growing weary in this work, and remind me that it is not in vain, for You are the Lord of the harvest.
I ask also, Lord, that You preserve Your church. Protect her from false teaching, sustain her in trials, sanctify her by truth. Let the preaching of the Word and the sacraments continually remind us of Your covenant promises. May Your people be strengthened to live holy lives, showing the world that they belong to You.
And when doubts rise or temptations press hard, lead me back to the certainty that I am Yours. Whisper to my soul the words of Psalm 100: “we are his people, and the sheep of his pasture.” Remind me that You will not forsake Your flock. Carry me in Your arms when I stumble. Feed me with Your Word when I grow faint. Shelter me under Your rod and staff when danger surrounds.
And Lord, keep me faithful until the day of Christ. Uphold me by Your covenant mercies. Let me run the race with endurance, not in vain, not in my own strength, but upheld by Your Spirit and guided by Your Word. And when the final day comes, gather me with all Your sheep into the eternal fold, where love will be perfect and joy complete.
In Jesus’ name I pray, Amen.
