A tremendous principle is revealed in the Book of Hebrews, starting at Chapter 6, verse 13, in relation to the New Testament or covenant that God has made with man. “When God made (His) promise to Abraham, because he could swear by no greater, he swore by himself” (Hebrews 6:13). Jesus Christ, our Lord, who died for our sins on Calvary’s cross, received a promise from God the Father which enables the sinful man to be reconciled to God and have a right relationship with God. God the Father and God the Son have made a covenant together so that we might receive this benefit through grace. The promise to Abraham was, “Surely blessing I will bless thee, and multiplying I will multiply thee” (Hebrews 6:14). And the Father swore by Himself, on the basis of His own integrity, for there is no one greater that could affirm His oath. After Abraham had patiently endured, he obtained the promise.
Hebrews 6:16-20 testifies of the “immutability of His counsel” (verse 17), and the perfect righteousness of our “forerunner” who has gone before us to the cross in our behalf.
God kept His agreement to bless mankind through the seed of Abraham. This is the nature and essence of the character of God in keeping every promise that He has made to us. It is upon the character of God that we are able to have an anchor for our souls.
