Apocalypse Explained #241
241. Verse 18. I counsel thee, signifies the means of reformation of those who are in the doctrine of faith alone. This is evident from what now follows, for the reformation of those who are in that doctrine is now treated of; therefore "I counsel thee" implies precepts as to how such must live that they may be reformed and thus saved.
Deuteronomy 7:25-26
25
You shall burn the engraved images of their gods with fire. You shall not covet the silver or the gold that is on them, nor take it for yourself, lest you be snared in it; for it is an abomination to Yahweh your God.
26
You shall not bring an abomination into your house, and become a devoted thing like it. You shall utterly detest it, and you shall utterly abhor it; for it is a devoted thing.
