We do not create God in the image of what we think He ought to be, or in an image that appeals to us or that suits our lifestyle. On the contrary, our worship of God must be informed by how He revealed Himself to us in the Word of God, the Bible.
Therefore, the death of Adam & Eve began from his spirit. What kind of death was this death? The scientific definition of death is to be cut off from all fellowship with the body. Therefore, for the Spirit to be declared died, does not mean that the Spirit is gone. It merely means that the Spirit has lost its keen knowledge of God and is dead to God. However, spiritual death means that there is no more fellowship with God. Consider, for example, a dumb person. It is not that this person does not have a mouth or two lungs. He cannot speak because there is some problem with his mouth. His mouth is dead to the human language.
When Adam & Eve disobeyed God His spirit didn’t died. The Spirit was still there, but it was dead to God and had lost its capacity to commune with God. When man sinned, this sin corrupted the keen intuitive knowledge of God, that existed in man’s spirit so that he became dead to the things of the spiritual realm. Thereafter, man may have religion morality, education, ability, power, and mental and physical health, yet he is dead to God. He can speak about God, conjecture about God, an even preach about God, yet he is dead to God. He can no longer hear or feel the voice of God’s Holy Spirit. This is why many times in the new Testament, God refers to those who live in their flesh as dead people ”
” But I say, walk and live ( habitually ) in the ( Holy ) Spirit ( responsive to and controlled and guided by the spirit ); then you will certainly not gratify the cravings and desires of the flesh ( of human nature without God ). For the desires of the flesh are opposed to ( Holy ) Spirit, and the ( desires of the ) Spirit are opposed to the flesh ( godless human nature ); for these are antagonistic to each other ( continually withstanding and in conflict with each other ), so that you are not free but are prevented from doing what you desire to do. But if you are guided ( led ) by the ( Holy ) Spirit, you are not subject to the Law. – Galatians 5: 16 – 18.
