ANSWER: "God also hath highly exalted Him, and given Him a name which is above every name: that at the name of Jesus every knee should bow, of things in heaven [angels], and things in earth [men], and things under the earth [demons]." Phil. 2:9, 109Wherefore God also hath highly exalted him, and given him a name which is above every name: 10That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; (Philippians 2:9‑10). If we confine ourselves to the passage itself, redemption is not in question either in the humiliation or the exaltation. If it were, demons would be saved too, which they will never be. This passage is quoted by some to prove a very bad doctrine. We often say when referring to this passage, how wondrous the grace that gives us to bow the knee, but what is spoken of here is not redemption, but subjugation.
In the end of Rev. 5, the "creatures... under the earth" are not infernal beings, but creatures under the earth. There redemption is celebrated: "Worthy is the Lamb that was slain." He is spoken of as a "little" Lamb in Revelation—unchanged in His character as the Lonely One, the unresisting One. "Led as a lamb to the slaughter." He is worshipped as the sacrificial Lamb.
