Revelation 14:5

Not that any liveth and sinneth not against God, but it is to be understood comparatively; they are without fault in comparison of the rest of the world, they have not in them the guile of hypocrisy, they are sincere. Or, possibly by guile is here understood a lie. All idolaters are liars, Romans 1:25, and idols are called lies, Jeremiah 16:19 Amos 2:4. Mr. Mede expoundeth this text by Zephaniah 3:13. The words may either more generally signify the holiness of these persons, in opposition to profaneness and hypocrisy; or more particularly, their freedom and purity from antichristian superstitions and idolatry.
