“Does God love Satan? Since we are to love our enemies, does that mean we should love Satan?”
No, God does not love Satan, and neither should we. God cannot love that which is evil and unholy, and Satan embodies all of that. He is the enemy (1 Peter 5:8); the evil one (Matthew 6:13); the father of lies and a murderer (John 8:44); the accuser of God’s people (Revelation 12:10); the tempter (1 Thessalonians 3:5); proud, wicked and violent (Isaiah 14:12-15); a deceiver (Acts 13:10); a schemer (Ephesians 6:11); a thief (Luke 8:12); and many more evil things. He is, in fact, everything that God hates. The heart of Satan is fixed and confirmed in his hatred of God, his judgment is final, and his destruction is sure. Revelation 20 describes God’s future plan for Satan, and love for Satan has no part in it.
Jesus’ command that we love our enemies (Matthew 5:44) is meant to govern interpersonal relationships in this world. We love God, and we love people (even our enemies), who are made in God’s image. Angels are not made in God’s image. We are never told to love the holy angels, and we are certainly never told to love the evil angels.
Since Satan is everything that is antithetical to the God we love, we cannot love Satan. If we loved Satan, we would be forced to hate God, because holiness is the opposite of sin.
God has already determined that there will be no forgiveness for Satan; we are the objects of God’s sacrificial love, shown on the cross. As God was lovingly redeeming mankind, He was putting Satan “to open shame” (Colossians 2:15). God’s judgment of Satan will be part of His great love for us.
