For he has made with me an everlasting covenant.2 Samuel 23:5
This covenant is divine in its origin. "He has made with me an everlasting covenant." Oh, that great word "he"! My soul, consider--God, the everlasting Father, has positively made a covenant with you; yes, the God who spoke the world into existence by a word; He, stooping from His majesty, takes hold of your hand and makes a covenant with you. Isn't this act so stupendous and such an example of condescension that it would overwhelm us forever if we could really understand it? "He has made with me an everlasting covenant."
A king has not made a covenant with me--that would be something; but the Prince of the kings of the earth, Shaddai, the Lord All-sufficient, the Jehovah of ages, the everlasting Elohim--"He has made with me an everlasting covenant."
But notice, it is particular in its application. "For he has made with me an everlasting covenant." Here is the sweetness of it to each believer. It is nothing for me that He made peace for the world; I want to know whether He made peace for me! It is a small matter that He has made a covenant; I want to know whether He has made a covenant with me.
Blessed is the assurance that He has made a covenant with me! If God the Holy Spirit gives me assurance of this, then His salvation is mine, His heart is mine, He Himself is mine--He is my God.
This covenant is everlasting in its duration. An everlasting covenant means a covenant that had no beginning and that will never, ever end. How sweet in all the uncertainties of life to know that "God's foundation stands firm,"1 and to have God's own promise, "I will not violate my covenant or alter the word that went forth from my lips."2 I will sing of this through all my days and at their ending and forever.
