Revelation 3:15 - Matthew Poole's English Annotations on the Holy Bible

I know thy works; I know and observe thy behaviour, thy ministerial function. That thou art neither cold nor hot; thou art neither openly profane and grossly scandalous, like heathens, or such as make no profession; nor yet hast thou any true zeal or warmth, either for the faith once delivered to the saints, or in love to God, seen in keeping his commandments, having the power and efficacy of godliness, teaching thee to deny all ungodliness and worldly lusts, Titus 2:12. Thou hast a form of godliness, but deniest the life and power thereof. I would thou wert cold or hot: we must not think Christ wisheth any persons cold absolutely, but comparatively, intimating to us, that the condition of a downright atheist, or profane person, is more hopeful than that of a close, formal hypocrite: the latter is in the road to hell as well as the other, and no more pleaseth God than the other. It is better not to have known the truth, than knowing it, to live contrary to it, Luke 12:48 2 Peter 2:21. Commonly such men also are proud, and self-conceited, having something to stop the mouth of their natural conscience, harder to be convinced of their evil state, Matthew 21:32,33.
