Why Another Covenant?
God first made the New Covenant with Adam. Then renewed it to Noah and his children forever:
“And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.” (Genesis 17:7).
Abraham and his decedents were to be saved under the New Covenant:
“Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of One, And to thy Seed, which is Christ.” “And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness.” (Galatians 3:16, James 2:23).
It is obvious that Abraham’s “decedents” would have included the Jews at Mount Sinai. So if they were already offered salvation under the New Covenant, why did God give them another covenant?
