I am Abraham. I am also called the progenitor of the Israelites, the father of many nations, and a friend of God because of my unconditional trust and faith in God, despite difficult circumstances. Therefore, God made me a promise and established His covenant with me. A covenant in preparation for the new covenant fulfilled by Jesus Christ.
Genesis 15:5: "Look toward heaven and count the stars, if you are able, for so your offspring will be."
Genesis 17:4-7: "Behold, my covenant is with you; and you shall be the father of a multitude of nations. And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be God to you and to your offspring after you."
The promises God made to me have ultimately been fulfilled in their entirety through Jesus Christ. Followers of Jesus are also called my "spiritual descendants." Through faith in Jesus Christ, they are incorporated into God's covenant.
I, too, belong to Jesus! As a human being, He may have come to earth after me, but long before that, I knew Him, and He knew me.
John 8:58: "Jesus said to them, 'Verily, verily, I say to you, Before Abraham was, I am .'"
