In the OT the Jews knew they were the chosen people and they lived under the promise of Genesis 12:3, “I will bless those that bless thee and curse those that curse thee…” This was an amazing promise of protection to Abraham and his seed, but this promise found an end in Jesus Christ: “… and in thee shall all families of the earth be blessed.”
Jesus Christ was the ultimate Chosen Person and the truth is that those who bless Jesus will be blessed and those that curse Jesus will be cursed, regardless of their genetic background. Furthermore, if you are “In Him” and have your name written in His Book of Life then you are Chosen as well. However, in the New Covenant God’s Chosen People don’t get to walk around like the OT Jews did saying, “We are the Chosen People! Don’t mess with us!” No indeed, in the New Covenant Jesus turns this promise into an obligation. Instead of having a smug self-righteous attitude we are to walk in humility and extend to others the very blessings that Jesus extended to us.
In Matthew 25 Jesus transforms the promise of Genesis 12 into an obligation that rests upon His true Chosen People. We are called to love those that are least loved in this world, and to identify the hungry, the thirsty, the sick, the strangers, the naked and the prisoners as Jesus Himself. Then those that bless Jesus will be blessed and inherit the Kingdom, whereas those that curse Jesus will themselves be cursed and cast into eternal darkness:
When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: And he shall set the sheep on his right hand, but the goats on the left. Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? When saw we thee a stranger, and took thee in? or naked, and clothed thee? Or when saw we thee sick, or in prison, and came unto thee? And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me. Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink: I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not. Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee? Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me. And these shall go away into everlasting punishment: but the righteous into life eternal. (Matthew 25:31-46)
Genesis 12:3 does not apply to the physical descendants of Abraham now that we live in the time of the New Covenant. The physical has been transformed into the spiritual and Jesus has ironically flipped it in Matthew 25. It is no longer a promise, but an obligation and a mandate for those who claim to be God’s people to love those who need God’s love the most.
