Theological question posited on FB: “Why did Jesus have to die? Is it correct or not to say: To reconcile us to a Holy God, we are saved from God, by God, for God’s glory[?].”
Without the shedding of blood there is no remission of sin (Leviticus 17:11; Hebrews 9:22). There is no blood from Adam forward that could atone for sin as man’s blood is tainted by the sin-nature as we’re all sinners and have fallen short of God’s standard of perfection (Romans 3:23). Even the blood of innocent animals in the Old Covenant Law did not provide remission-atonement for sin (Hebrews 10:4); therefore, Jesus Christ, at the assigned point in history, entered Time through the womb of a virgin woman and thereby bypassed the sin-nature that passed genomically through the seed of the man (Adam) to all of mankind because in Adam, all die (1 Corinthians 15:22; Romans 5:12-21).
Jesus therefore entered into the World absent a sin-nature as Jesus is both fully God and fully man through the hypostatic union (Philippians 2:8; John 1). Jesus lived a perfect life of sinlessness (2 Corinthians 5:21) and Jesus fulfilled the Law of Moses and the Commandments with perfection (Matthew 5:17), something that no sinful man could do and His blood was perfect, innocent, thereby making Jesus the ONLY acceptable sacrifice for our sin as Jesus is the ONLY “begotten” of the Father, the unique One…the One and only.
When Jesus gave Himself to be sacrificed for our sin on that Cross on Golgotha, His blood streamed down the upright of that Cross and His blood dripped into the sands outside the Old City of Jerusalem and God the Father looked at the blood of His dear Son and decreed that anyone who would trust in that precious innocent Blood for the atonement of sin and believe that Jesus Christ died for them to pay their sin-debt, that person so believing with a sincere heart would be saved from God’s wrath, forgiven of sin, redeemed from death in sin and death in Hell and God the Father promises to impute the perfection of His dear Son over the life of anyone who will trust in Jesus as their Lord for the Mediation of sin and the Father will give that person His precious indwelling Holy Spirit to sanctify them in Truth and walk them in the life-long process of sanctification thereby incrementally transforming them into the spiritual image of the Son, Jesus Christ, while God prepares His faithful children for service in the Kingdom of God (John 3:16; Ephesians 1:13-14; John 14:16).
Without Jesus Christ as our Mediator for sin, mankind dies in sin and dies in Hell because God the Father is NOT going to permit unrepentant sin to enter His Kingdom subsequent to the death of the body in Time (Revelation 21:27); therefore, mankind will deal with sin during the Age of Grace through faith in Jesus Christ as Lord and Mediator for sin (John 3:16) – or – mankind will deal with sin in Eternity at the Judgment of the Condemned and lose both body and soul in Hell (Revelation 20:11-15; Matthew 10:28). There are no other options available.
