Not many people understand the meaning and purpose of the crucifixion of Jesus. Some believe it was unnecessarily cruel that God would insist that Jesus be subject to crucifixion and death. They recall with compassion his plaintive New Testament plea to God, "Is there any other way to accomplish your purposes?" Others believe that Jesus merely fainted on the cross and was later revived, or regained consciousness while lying in the tomb. Irrespective of your beliefs about the cross and the crucifixion of Jesus, know with certainty that it is only through death that we can gain life to the full.
As an example, a parasite generally is destroyed when the host dies. Adam and Eve were rendered hosts to Satan's parasitic spiritual energies. The transgression in the Garden of Eden was of such a profound magnitude, and caused such irreversible corruption in the human spirit, that only in death could Adam and Eve and all of humanity be made whole. Only in death could the corruption in their spiritual DNA be excised. In death, the indwelling Holy Spirit can then selectively give new life to the spiritual parts of us that are of God. As of now, while everyone is born subject to spiritual death, the death will not occur until the final judgment when souls must give an account for their lives. In the meantime, we can repent, seek God's forgiveness, and thereby avoid spiritual death.
Because Jesus did not commit any sin or transgression of spiritual law, when he went into hell after his crucifixion and preached redemption to the prisoners of hell, hell had no power to hold him. His freedom was mandated. He was free and immune to death. He thus became the spiritual fix for the human DNA; the fix with the capacity to render others immune to hell and spiritual death. Appropriating the fix involves a deliberate choice to voluntarily put to death the things of the devil, including all negative spiritual energies such as hatred, arrogance, pride, immorality, greed, debauchery, slander, deception, gossip, betrayal, envy, jealousy, lust, and the thoughts that accompany them. We then receive the indwelling Holy Spirit and rely on him to give new life to the parts of us that are of God including love, joy, peace, patience, gentleness, truth, and self-control. We experience true life.
