Why doesn't God give fallen angels the opportunity to repent?

from the old testament

• Satan, an angel, rebelled against God out of pride, desiring to be exalted above Him (Isaiah 14:12–15; Ezekiel 28:12–17). Satan’s use of "I will" in Isaiah 14:13–14 indicates his choice to rebel, demonstrating angels’ capacity to choose their path. This occurred before the creation of humanity, with no opportunity for salvation given.
• Satan was immediately punished by being cast away from the presence of God unless given permission to briefly return (Isaiah 14; Ezekiel 28; Revelation 13). Fallen angels, including Satan, were previously already in God's presence (Ezekiel 28:14). In their rebellion, they were judged by being removed from eternity with God.
• Satan was further punished after causing Adam and Eve to rebel (Genesis 3:14–15).

from the new testament

• The fallen angels are set in their rebellion. We see this in the wandering spirit who continues in its rebellion that Jesus talks about: "When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, but finds none. Then it says, 'I will return to my house from which I came.' And when it comes, it finds the house empty, swept, and put in order. Then it goes and brings with it seven other spirits more evil than itself, and they enter and dwell there, and the last state of that person is worse than the first" (Matthew 12:43–45).
• No sacrifice was planned to redeem the sins of fallen angels. Scripture only teaches that Christ came to die as a sacrifice for the sins of people. Hebrews 2:14–17 makes clear, "Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death, that is, the devil, and deliver all those who through fear of death were subject to lifelong slavery. For surely it is not angels that he helps, but he helps the offspring of Abraham. Therefore he had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people."
• Romans 5:6 confirms that this redemption is unique to humanity: "For while we were still weak, at the right time Christ died for the ungodly."
• First Peter 1:10–12 also confirms that God’s plan of salvation through Christ is uniquely for humanity. It reveals that angels do not share in this grace.
• Second Peter 2:4 and Jude 1:6 describe angels who sinned and were punished before humanity’s creation for their rebellion and impact on humanity.
• Revelation 12:3–4 depicts Satan and fallen angels being cast out of heaven after their rebellion, emphasizing their choice to side with evil, again with punishment for this decision and no opportunity to be saved from this decision.
• Satan’s judgment is sure. He will be eternally separated from God in punishment for his rebellion (Revelation 20:9-10).
• Instead of being given an opportunity to repent during their lifetime, angels do not die. Those "elect angels" (1 Timothy 5:21) remained faithful while the fallen angels did not.

implications for today

Reflecting on why fallen angels are not given an opportunity to repent, it's clear that God's plan of redemption is uniquely tailored to humanity. Unlike us, angels do not experience death, which means they do not have a temporal state in which repentance could occur. Their rebellion, characterized by a definitive and irrevocable choice against God, results in eternal separation from Him. For us, this serves as a powerful reminder of the importance of our choices and the precious gift of redemption offered through Christ. It calls us to value our relationship with God, understanding that our decisions have profound implications. It also calls us to respond to and embrace the grace we’ve been given with gratitude and wholehearted living for God.
