Why are God's covenants with the patriarchs settled and unchangeable?
God's covenants with the patriarchs are settled and unchangeable because God Himself made them. Once confirmed, no man can annul or add to them. Even after thousands of years, they remain absolute; no one can abridge them, and they are settled forever.
Les teaches that Paul uses the analogy of a man's covenant in verse 15: if it is confirmed, no man disannulleth or addeth to it. When God made a covenant with Abraham, David, Isaac, or any of the other patriarchs, none of those great men could take away a single word or add to it. It stood settled in concrete because God was the one who made it. Even though thousands of years may have elapsed, these covenants are still absolute. No one can annul them, no one can abridge them, they are settled forever. The promises were made to Abraham and his seed, not to many seeds, pointing to the line that would bring the Messiah.
Brethren, I speak after the manner of men; Though it be but a man’s covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.
