Now to Abraham and his Seed were the promises made. He does not say, “And to seeds,” as of many, but as of one, “And to your Seed,” who is Christ.
The apostle Paul highlights the spiritual promises given to Abraham, the father of the faithful. God had given Abraham wonderful physical promises of land and a multitude of descendants, as well as the even more amazing spiritual blessings that would come through our loving Savior. Jesus Christ’s death made it possible for our sins to be forgiven so we could be offered salvation and eternal life in God’s Kingdom.
In Genesis 22:18, after Abraham had shown he was willing to trust God with the life of his son, God said, “In your seed all the nations of the earth shall be blessed.” This will have its ultimate fulfillment after Jesus Christ’s second coming when all nations will begin to have the opportunity for both physical blessings and, more importantly, the spiritual blessings of conversion and becoming children of God.
