Galatians 3:15-18 Part 1 of 3

Brothers and sisters, let me take an example from everyday life. Just as no one can set aside or add to a human covenant that has been duly established, so it is in this case. The promises were spoken to Abraham and to his seed. Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ. What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise. For if the inheritance depends on the law, then it no longer depends on the promise; but God in his grace gave it to Abraham through a promise. 

Brothers and sisters 
Romans 7:1  Do you not know, brothers and sisters--for I am speaking to those who know the law--that the law has authority over someone only as long as that person lives?

The promises were spoken to Abraham and to his seed 
Genesis 17:19  Then God said, "Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him."
Psalm 132:11  The LORD swore an oath to David, a sure oath he will not revoke: "One of your own descendants I will place on your throne."
Micah 7:20  You will be faithful to Jacob, and show love to Abraham, as you pledged on oath to our ancestors in days long ago.
Luke 1:54-55  "He has helped his servant Israel, remembering to be merciful to Abraham and his descendants forever, just as he promised our ancestors."
Romans 4:13  It was not through the law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith.
Romans 4:16  Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham's offspring--not only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all.
