"It is men of this world, sinful men, whom Christ sanctifies--He is the Sanctifier. And He and these are all of one.
Therefore Christ became man;
He takes the place of man;
He was born as man is born.
In His human nature, Christ came from the man from whom we all have come; so that the expression in this verse, "all of one," is the same as "all from one,"--as all coming forth from one.
One man is the source and head of all our human nature. And the genealogy of Christ, as one of us, runs to Adam. Luke 3:38."
