“The Lord God took the man and placed him in the orchard in Eden to care for it and to maintain it. Then the Lord God commanded the man, ‘You may freely eat (fruit) from every tree of the orchard, but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will surely die.'”Genesis 2:15 – 17, NET
The literal meaning of “you will surely die” is “dying you will die” which implies two deaths. The above, very likely, refers to the death of the body followed by the death of the spirit. The spirit of humankind is its life. Jesus stated: “The spirit is the one who gives life; the flesh counts for nothing.” Our spirit (intelligence) is our life and our identity. “For when you eat…” means “in the very day you eat…” The law of intelligence, or the law of the spirit, as we currently understand it requires that if intelligent beings violate a specific command, they must die forever instantly.
God, because He loved the humankind so much, delayed the consequence of disobedience until, in the fullness of time, the promised Grace is a reality. From the day the humankind disobeyed in the orchard in Eden until the cross at Golgotha was the period of grace that preserved the humankind until the death sentence could be carried out in the body of Jesus Christ on the cross at Golgotha.
Jesus conquered temptation. Thus He had a perfect spirit – perfect life. The perfect life of Jesus Christ is the new life of the humankind. On the cross at Golgotha Jesus set aside His perfect and eternal life, and God put in Jesus the spirit, or life, that disobeyed in the orchard in Eden. Then, by abandoning or forsaking Jesus, God destroyed sin and the sinful life of the humankind forever. Jesus’ body did not begin to decay because it was a sanctified body. Now, the faithful ones, the yielded believers, have the new spirit, new life, the perfect spirit of Jesus Christ. When Jesus returns, the faithful will also have Jesus’ body forever.
