The body without the spirit is dead. Man was made up of the body (flesh), soul and spirit. Adam died in the spirit on the day he disobeyed God’s commandment not to eat of the tree of the knowledge of good and evil.
Adam’s death is the death of all mankind; as such every man born of a woman inherited death from Adam.
The natural man is a dead man. His spirit is separated from God by the disobedient of Adam to God’s commandment. Adam’s disobedience brought a spiritual death upon mankind. This spiritual death is the first death; it is the exit or departure of man from the nature of God (divinity) into the nature of sin (carnality). Every man inherited this first death from Adam.
The second death is the natural death. This is the departure or exit of man from this natural realm of existence.
The Bible says that the wages of sin is death. Death is the debt every sinner (natural man) is owing. The soul of every sinner is destined to everlasting damnation. This is the last death.
Jesus died on behalf of the sinner. Jesus died the death the sinner is destined to die. Jesus paid the price the sinner is owing.
The death of Jesus on the cross of Calvary was the ransom paid for the redemption of mankind from everlasting damnation. The cross was a transaction for the salvation of the souls of mankind from the last death.
Jesus took the sins of the whole world and nailed it to the cross. He died to set man free from the death sentence upon his life.
Man is not liable to die again because of the death of Jesus. The Bible says for God so loved the world that He gave His only begotten son that whosoever believes in Him shall not die but have everlasting life.
Jesus died for the whole world. He died for all mankind. He died for all sinner. He died that the sinner should be saved.
The free gift of salvation is accessible to all through faith. In other words, anyone who believes in the finished work of Jesus Christ at the cross of Calvary shall not die. Any one who believes in Jesus Christ shall not experience the last death.
