The Bible makes it clear that God is sovereign. It also makes clear that, in some way, He has elected certain people to be His people and to live out the purposes He has for them. Although we do not know exactly how this works with our decisions, it is clear that election is a biblical doctrine. Angels were created with a will as well, yet some of them sinned and rebelled against God. The Bible tells us that salvation is for humanity and not the angels; therefore, based on that and the fact that Scripture does not give us any more examples of angels rebelling, we can assume that their rebellion was a one-time thing. No more of the angels can sin, and the ones who did sin will receive their punishment in the lake of fire. Humanity, on the other hand, has the ability to reject or receive Christ until they die. We are called to respond to God’s call of salvation while there is still time.
The question of whether more angels could sin encourages us to reflect on the nature of free will and the consequences of rebellion against God. While Scripture indicates that angels who rebelled, Satan and his followers, have made irrevocable choices, it reminds us that we, too, are endowed with free will and the responsibility to choose righteousness. This understanding invites us to be vigilant in our spiritual lives, recognizing that the decisions we make can have lasting implications for our relationship with God. Thankfully, we have a choice that is not permanent until we are no longer alive. As long as we live, God wants us to turn to Him (1 Timothy 2:3–4; 2 Peter 3:9). Instead of putting this response off, we should respond to God’s call to salvation, knowing that we are not guaranteed tomorrow. And if we are saved, we should walk in the Spirit (Romans 8) and abide in Christ (John 15), seeking to walk in obedience because of our love for Him and not in rebellion, as the fallen angels did.
