Perhaps we don’t think of covenants very often, but we use them, especially when something serious calls for a commitment such as marriage or a financial obligation. Merriam-Webster defines the word covenant as “a usually formal, solemn, and binding agreement.” In Scripture, covenants are sometimes accompanied by blood, demonstrating the judgment that would fall upon those who break such a serious agreement.

In our modern time, however, covenants are not always so highly regarded: people enter marriage with a prenuptial agreement, already planning ahead in the event of divorce. Businesses employ lawyers to help them navigate or exit agreements if the need arises, and a general view of doing what is best and convenient for oneself takes precedence over doing what is true to your word, honorable, or promised if it is no longer to one’s benefit.

In a world where broken promises are common, we need to reassure our hearts that our God keeps each promise and covenant he makes.

God establishes covenants with his people and remains faithful to them.

In Scripture we read about covenants the Lord makes with his people—for example, with Abraham in Genesis 15 and 17 and with David in 2 Samuel 7. And while theologians explain the multiple levels of how these covenants are fulfilled, or are being fulfilled, we consistently find that God does not forget to act upon them. Psalm 105 is a beautiful psalm that reminds God’s people of his faithfulness to them and encourages them to break forth in praise:

Oh give thanks to the Lord; call upon his name;
    make known his deeds among the peoples!
Sing to him, sing praises to him;
    tell of all his wondrous works!
Glory in his holy name;
    let the hearts of those who seek the Lord rejoice!
Seek the Lord and his strength;
    seek his presence continually!
Remember the wondrous works that he has done,
    his miracles, and the judgments he uttered,
O offspring of Abraham, his servant,
    children of Jacob, his chosen ones! (Ps. 105: 1-6)

This psalm begins with praise and then recounts the faithfulness of God to his people, reminding them of the living God who keeps his promises and covenants. History itself attests to the character of God. The Westminster Shorter Catechism summarizes that “God is a Spirit, infinite, eternal, and unchangeable, in his being, wisdom, power, holiness, justice, goodness, and truth” (WSC Q. 4).

It is the character of God, then, that makes a covenant with him so special. A promise made by a good, holy, true, wise, powerful God, who is also infinite and eternal, is a promise that can be trusted.

God’s unchanging character guarantees that his promises will never fail.

God will not be looking for loopholes to escape a covenant promise. He will not change his mind when he has given his word. In fact, it is who God is that keeps his people safe in him. There are too many times that our behavior does not deserve faithfulness, yet God does not change who he is because of us.

It is this reality that the Psalmist proclaims in Psalm 106 when he reflects on the disobedience and long history of great spiritual rebellion of the Israelite people, and yet rests in God’s faithful love to save them, even after his discipline:

Both we and our fathers have sinned;
    we have committed iniquity; we have done wickedness. (Ps. 106:6)

Nevertheless, he looked upon their distress,
    when he heard their cry.
For their sake he remembered his covenant,
    and relented according to the abundance of his steadfast love.
He caused them to be pitied
    by all those who held them captive. (Ps. 106: 44-46)

God remains faithful to his covenant even when his people are unfaithful.

This is the Lord we serve, a faithful God, who binds himself to his people and will not let them go:

“I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one.” (John 10:28-29)

Because of who God is, we can look to Scripture and learn about God’s promises that grant salvation: his covenant of grace (how God grants salvation and life to sinners by the work of Jesus), and his covenant of redemption (a covenant between the persons of the Trinity—Father, Son, and Holy Spirit—to accomplish salvation for sinners like you and me and myriads of others).

We can rest in these promises and covenants, for he has given us abundant proof that he is dependable, showing that our Lord is indeed true and faithful and good:

Praise the Lord!
Oh give thanks to the Lord, for he is good,
    for his steadfast love endures forever! (Ps. 106:1)
