Exodus 19:6
And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
1 Peter 2:9
But you are a chosen race who serve as Priests for The Kingdom, a holy nation, a redeemed assembly; you should proclaim the praises of him who called you from darkness into his excellent light.
Revelation 1:6
To him who loves us and has freed us from our sins by his blood, and has made us to be a kingdom of priests to serve his God and Father””to him be glory and power for ever and ever! Amen.
Galatians 4:22-31
For it is written: "Abraham had two sons, one from a Maidservant and one from a Freewoman." But he who was from the Maidservant was born of the flesh, but he who was from the Freewoman was by The Promise. But these are illustrations of the two Covenants, the one that is from Mount Sinai begets to bondage, which is Hagar. For Hagar is Mount Sinai that is in Arabia, and agrees with this Jerusalem and is serving in bondage and its children. But that Jerusalem above is free, which is our mother.
For it is written: "Rejoice, barren one, she who does not bear, triumph and shout, she who does not give birth, because the children of the desolate have increased more than the children of a wife."
But we, my brethren, are children of The Promise like Isaac. And as then, he who was born by the flesh did persecute him who was of the Spirit, so it is now also.
But what do the Scriptures say? Cast out the Maidservant and her son because the son of the Maidservant will not inherit with the son of the Freewoman.
We therefore, my brethren, are not children of the Maidservant, but children of the Freewoman.
John 1:11-13
He came to His own, and His own did not receive Him. But to all who did receive Him, to those who believed in His name, He gave the right to become children of God”” children born not of blood, nor of the will of the flesh, nor of the will of man, but born of God.
