The True "Walking Dead"

“For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.” (Romans 6²³)
“And this is eternal life, that they may know You, the only true God, and Jesus Christ whom you have sent.” (John 17³)

                If eternal life begins here on earth when one comes to know Christ, is it possible that the death caused by sin could also begin while one is living? I believe it can. It says in 1 Timothy 5⁶ concerning the young widows that “she that lives in pleasure is dead while she lives.” If it is possible for them I believe it to be possible for all humanity. If darkness is lack of light and hell lack of God then death could also be defined as lack of life. Life comes from Jesus Himself. In John 10¹⁰ is says that He came to give us “life and life in abundance.” We always seem to think about a physical death when these terms are used, but that is not always the case. For example, He also said in the garden that the cost for having eaten the fruit was death, yet they lived for hundreds of years. If when Jesus spoke of life the majority of the times He was not speaking of our physical life span, why do we automatically take it that way when He spoke of death? It is possible that just as He was speaking of eternal life in John that Romans was also referring to an eternal death? Death that could begin in the daily life that we live?
