The Everlasting Covenant
How the Covenant was Confirmed
The conclusion is equally simple. God made a covenant with Abraham, and confirmed it with a oath. “Men verily swear by the greater; and an oath for confirmation is to them an end of all strife. Wherein God, willing more abundantly to show unto the heirs of promise the immutability of His council, confirmed it by an oath; that by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold on the hope set before us.” 1 Therefore that covenant, which was confirmed in Christ by God’s oath pledging His own existence to its fulfillment, could never afterwards be changed one iota. Not one jot or tittle could pass from it or be added to it while God lives. EVCO 300.3
Note the statement that “to Abraham and his seed were the promises made.” And the seed is Christ. All the promises to Abraham were confirmed in Christ. “Promises,” remember, and not simply a promise. “For how many soever be the promises of God, in Him is the yea; wherefore also through Him is the Amen, unto the glory of God through us.” 2 EVCO 301.1
