The death and resurrection of Jesus Christ has conquered the last enemy, Death. Death and Hell are the last persons thrown into the lake of fire before the establishment of the New Heaven and the New Earth of the eternal state, in which Sin , Death and the Devil are no longer present at all. Life with God can be enjoyed forever to the full without interference.
Death = Separation. Physical death is the separation of the soul from the body; spiritual death is the separation of the soul from God; eternal death is the separation of the soul and body from God forever.
Deliverance from death produces profusive praise and effusive thanks. First, deliverance from premature death brings relief: “Return to your rest, O my soul.” Then, appreciation: “I will walk before the Lord in the land of the living.” Finally, gratitude: “What shall I render to the Lord for all his benefits to me?…I will take the cup of salvation…I will pay my vows unto the Lord.”
My death is “precious” to God, that is, costly and dear, because He desperately does not want to be separated from me, at all, ever. Therefore, He sent His Son to unite me to live with Him forever.
