Colossians 2:10

Treasury of Scripture Knowledge

And ye are complete in him, which is the head of all principality and power:

where there can't be Greek and Jew, circumcision and uncircumcision, barbarian, Scythian, bondservant, freeman; but Christ is all, and in all.

From his fullness we all received grace upon grace.

But of him, you are in Christ Jesus, who was made to us wisdom from God, and righteousness and sanctification, and redemption:

For you are all children of God, through faith in Christ Jesus.

Having been made perfect, he became to all of those who obey him the author of eternal salvation,

They will by no means follow a stranger, but will flee from him; for they don't know the voice of strangers."

since indeed there is one God who will justify the circumcised by faith, and the uncircumcised through faith.
