When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, saying, “I will surely bless you and give you many descendants.” And so after waiting patiently, Abraham received what was promised.
People swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument. Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope set before us may be greatly encouraged.We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain,where our forerunner, Jesus, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
Hebrews 6: 13-20
Carefully follow the steps God took to lay for us an infallible foundation of faith and a sure anchor for our souls. First is the promise of God, but then he went further and elevated the promise to an oath, which was the deepest he could go under the old covenant. But in our dispensation, the promise, the oath is taken deeper and sealed in the blood of Jesus by which we have access into the very presence of God.
The foundation for strength, victory, and power has been laid, the way is open and inviting, and we must seize the chance and maximize the blessed possibilities of the promise, the oath, and the blood of Jesus.
