Question posited on FB: “Why Did Jesus Come to Earth?”
Jesus Christ entered the Realm of Time for the sole purpose of “destroying the works of the Devil” (1 John 3:8b). Jesus was commissioned by the Father (John 3:35) to take elements from the unseen Spiritual World and fashion those elements into matter that can be apprehended by life constrained by Time and physics (Hebrews 11:3) and subsequently create the Heavens and the Earth with rapidity in six-literal 24-hour days (John 1; Colossians 1; Genesis 1).
The Heavens and the Earth were created in direct response to the coup d’état initiated by a rebellious cherub angel in the Kingdom of God (Ezekiel 28:11+; Isaiah 14) and God the Father extricated this rebellious angel from the Kingdom where nothing impure is permitted to exist (Rev. 12; Luke 10:18; Rev. 21:27) and placed him upon the Earth at which time Elohim proclaimed a declaration of war between the rebellious angel and the virgin born Son, Jesus Christ (Genesis 3:15); therefore, Jesus entered Time to defeat the works of the Devil for you and for me i.e. death, Hell, the grave while God demonstrates the horror of sin and disobedience to the faithful angelic creation in the Kingdom. That war is presently observed in Time manifesting between Islam-Allah (Satan) and Israel.
For all intents and purposes, had Lucifer not rebelled in the Kingdom of God and introduced sin into same (Revelation 21:27), it is most probable that God would have never created the Heavens and the Earth, our human genome and subsequently tolerated 6000-years of an obstinate, sinful, stubborn, people (Genesis 6:5).
