Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Romans 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
I truly do not believe we understand the definitive results of sin. Death is a result of sin. People seem to overlook the realization of what happened in the garden following the fall. God told Adam that if they ate from the tree of knowledge of good and evil the results would surely be death. Death is the cost or “wage” of sin. The severity and finality of death should help us understand God’s true feelings toward sin. When Adam sinned then death passed upon every person. Death became a certainty for every human in the known world from that point forward.
Cancer, disease, viral infections, murder, hunger, starvation, and other horrific forms of death are all results of sin. Please understand that if this is the result of sin then it should give us all a good idea of how God views sin. You might be thinking this is a little extreme for just one simple mistake. Please take a moment to consider the grace that God has extended through all this. He created man in His image, placed him in a perfect utopia without any knowledge of good or evil, and gave him one command. Man disobeyed that command and rather than dying immediately God came into the garden, killed an animal to clothe man’s nakedness, and created a redemptive plan to restore humanity back to himself through the death, burial, and resurrection of his own Son, Jesus Christ. I tend to believe that as horrific of a thing such as death is it could have been a lot worse.
When sin entered into the world it also created a decaying effect. While the world is slowly deteriorating, death becomes more and more severe. Life is now one of the most uncertain experiences on earth. We have to make our election and calling of God sure. We have to run our race effectively. We have to make the most of this life. It is but a vapor that appears for a moment and vanishes away.
