Hebrews 2
11 Both he that sanctifies and they who are sanctified are all of one.
"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."
