Theological question posited on FB: “Why didn’t God kill or destroy Satan?”
God the Father, for some unknown reason, truly desires a loving and honest relationship with His created beings and in order for love and relationship to manifest in purity with authenticity, those involved in that relationship must possess the free will to choose to love or hate, honor or dishonor, they must possess the free will to pursue that relationship or reject it; if the participants are programmed or coerced to comply…love and relationship become impotent because love cannot be realized by force or coercion nor can love be realized in fear.
If God the Father had simply destroyed Lucifer and the rebellious angels that followed Lucifer in His coup d’état, the unfathomable number of faithful angels that remained would no longer love God out of free will/volition but out of fear; again, true love and relationship cannot exist or be realized in an atmosphere of fear; therefore, the Scriptures tells us that before the beginning of Time (2 Timothy 1:10), God the Father ordained that the Gospel would be the method by which He would deal with Lucifer and the rebellious angels while maintaining volitional love with His faithful angelic creation.
The Holy Spirit tells us that God the Father commissioned the Son, Jesus Christ (John 3:35), to take elements from the unseen Spiritual World (Hebrews 11:3) and fashion those elements into matter that can be apprehended by life constrained by Time and physics. Our Creator, Jesus Christ, proceeded, with rapidity, to create Time, the Universe, Earth, the human genome (Colossians 1:15-18; John 1; Genesis 1) and God the Father then placed Lucifer on the Earth and within Eden (the Garden of God) (Ezekiel 28:11-17). This was done in order to remove from the Kingdom the destructive sin introduced by Lucifer into the Kingdom through rebellion and deal with that sin apart from the Kingdom and within the constraints of Time.
Lucifer was successful in tempting Eve to compromise with evil and Eve was successful in tempting her husband, Adam, to compromise with evil and this began the war between Lucifer v. Yeshua as articulated by the Spirit in Genesis 3:14-15; in fact, the Holy Spirit tells us that the primary reason the Son of God, Jesus Christ, entered Time was to defeat the works of the Devil (1 John 3:8b). Lucifer was essentially defeated by Yeshua at the Crucifixion some 4000-years subsequent to Genesis 3:14-15 but that struggle continues and can be seen today between the spiritual and physical armies of Allah-Satan/Islam v. Yeshua-the Christian-the Jew/Israel.
The spiritual warfare that surrounds us, the death and carnage caused by Satan and SIN is demonstrating to the faithful angels in the Kingdom why God the Father extricated the sin of Lucifer from the Kingdom and why sin cannot be tolerated and why SIN can NEVER enter the Kingdom of God (Revelation 21:27). The Holy Spirit explains that at the end of the Millennial Reign of Messiah-Yeshua, the faithful angels in Heaven will fully concur with God the Father that Satan and the fallen angels (demons) do deserve punishment in Hell forever (Revelation 20:10).
God the Father through the Son, Jesus Christ, will have demonstrated His incredible love for His created beings, both angelic and human, by having given Himself as a sacrifice for sin; it is through selfless love and sacrifice for those He loves that God will maintain volitional love with His faithful angels that He has cherished from Eternity past; mankind, that has trusted in what Jesus Christ has done on the Cross of suffering, will also enjoy the love and fellowship of God forever in the Kingdom.
