The Word never differs = "Jesus Christ the same, yesterday, today and forever" Hebrews 13:8
The
instructions from the Lord were
preparatory for His Coming in the flesh.
Therefore, when He came into the world, He said:
“Sacrifice and offering You did not desire,
But a body You have prepared for Me.
6In burnt offerings and
sacrifices for sin
You had no pleasure.
7Then I said, ‘Behold, I have come—
In the volume of the book it is written of Me—
To do Your will, O God.’ ”
8Previously saying, “Sacrifice and offering, burnt offerings, and
offerings for sin You did not desire, nor had pleasure
in them” (which are offered according to the law),
9then He said, “Behold, I have come to do Your will, O God.” He takes away the first that He may establish the second.
10By that will we have been sanctified through the offering of the body of Jesus Christ once
for all.
Keep this in the forefront of your mind and heart = "The Word became flesh and dwelt among us"
