Question was asked: Why was Satan extricated from the Kingdom?
Satan was extricated from the Kingdom, as were the angels who followed Satan in his rebellion against God, because sin, nothing impure, is permitted to exist in God’s Kingdom (Rev 21:27) and the destructive nature of Satan’s sin was removed and Jesus was commissioned by the Father (John 1; Hebrews 1; Colossians 1; John 3:35) to take elements from the unseen Spiritual World and fashion those elements into matter (Hebrews 11:3) and create the Heavens and the Earth with haste (six-literal days-YOM) and Satan, the fallen angels, were placed upon this Earth some 6022-years ago to be dealt with by God through selfless love as per Genesis 3:15-21; 1 John 3:8b)…this is why Jesus entered the created realm of Time as Jesus tells us that His Kingdom is NOT of this World (John 18:36).
Our entire creation pertaining to Time and Matter and Physics is the resultant of Satan’s rebellion and God’s desire to maintain volitional love with His faithful angelic creation that He loves beyond human understanding…this love is contingent upon free will and free will, volitional love, is God’s desire.
All of the evil and suffering and death that has transpired over the previous 6000-years is the resultant of a cosmic war having been removed from the Spiritual Kingdom and placed upon this Earth constrained by Time and Physics to be dealt with apart from the Kingdom and we are players, participants, in this war and we choose whom we will serve through our loyalty to God the Father through faith in Jesus or faithfulness to the Devil in unbelief. We will be judged accordingly and the allies of Satan will be destroyed in the “second death” (Revelation 20:11-15) and the allies of God will receive life in the New Jerusalem and serve Jesus Christ, forever (2 Timothy 2:12).
