This out of context verse comes to me often, and Im surprised at other Christians that can’t righty divide it.
This is God speaking to ABRAHAM
Genesis 12:3
“And I will bless those who bless you [Abraham], and those who curse you [Abraham] I will curse. And all families of the earth will be blessed in you.”
God is specifically telling Abraham He will bless those that bless him, Abraham. Not that He will bless the modern state of Israel or those that call themselves “Jews”. They way God will ‘bless the families of earth’ is by God’s Son, Jesus.
Genesis 22:18
And in thy seed [Jesus] shall all the nations of the earth be blessed, because thou [Abraham] hast hearkened to My voice.
Paul exegetes this verse for us in the New Testament:
Galatians 3:16
Now to Abraham and to his Seed were the promises spoken. He does not say, “and to your seeds,” as of many; but as of one, “and to your Seed,” which is Christ.
So we see the “Seed” is Jesus Christ.
John 8:39
They answered and said to Him, “Our father is Abraham.” Jesus said to them, “If you were Abraham’s children, you would do the works of Abraham.
Those that claim they are the Children of promise must be doing the works of Abraham. It has nothing to do with bloodline. We can’t rely on our flesh to save us on Judgement day.
Galatians 3:28
There is neither Judean nor ethnic; there is neither bond nor free; there is neither male nor female; for you are all one in Christ Jesus.
And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.
Acts 3:25 -26
You are the children of the prophets and of the covenant that God Himself appointed to our fathers, saying to Abraham, ‘And in your seed shall all the families of the earth be blessed.’
Unto you first has God, having raised up His Son Jesus, sent Him to bless you in turning each of you from your wickedness.”
Almighty Father, thank you for being faithful to your promises and for making us into a people for your own possession. Bring us safely into the land of rest you promised to our father Abraham!
