this word, it is because there is no light in them.” Isa. 8:20.
The Lord by His prophet gave the foregoing rule as an infallible test for detecting certain systems of error now prevailing.
In verse 16 we find the following order:—“Bind up the testimony, seal the law among my disciples.”
We cannot imagine that God left so important
an instrument as His law without a seal,
and then required man to affix one to it.
--The Lord sealed His own law,
----but man has removed the seal,
------and it is now to be restored.
The law must be sealed among His disciples, for it is among them that the seal has been removed.
And as with the law, so with “the testimony.”
Violence has been done to both in the professed church of Christ.
The work of restoration is pointed out in the prophecies of the New 
Testament. But this is not accomplished without opposition, for thus speaks the prophet:—“And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.” Rev. 12:17.
An explanation of the last expression is given in Rev. 19:10, which says, “The testimony of Jesus is the Spirit of prophecy.”
Hence in the last days there will arise those who have these peculiarities:
--they will keep the commandments of God, which have been rejected or dishonored—they will restore the seal to the law, and thus present it to the world a perfect and complete instrument; --and they will have the testimony of Jesus, which is the Spirit of prophecy—they will “bind up the testimony,” which has been torn from its place in the church of Christ."
