death by sin
Romans 5:12
5:12 death by sin. Thus there was no death before sin entered the world. The finished creation was “very good” (Genesis 1:31), with an abundance of food and all other provisions for man and the animals. There was certainly no struggle for existence, or survival of the fittest, for every creature was created fit for its own environment. When Adam sinned, God brought the curse of decay and death not only upon Adam but also upon all His dominion (Genesis 3:17-19). See also I Corinthians 15:21-22; Romans 8:20-22.
