Is it possible to separate the sin from the sinner? See it sounds nice to say “God loves the sinner, but hates the sin.” But is it possible? Yes and no. Don’t you hate answers like that? However, if you are a believer you shouldn’t.
Sin cannot be separated from a sinner. Sin only exists in theory until there is an entity to commit sin. God created the world and all that was in it. He declared it was good, even then though the idea or concept of sin existed. Remember that Christ was slain before the foundation of the world and the names were written in the Book of Life (Rev 13:8). So the concept of sin and evil existed from the foundation of the world, otherwise there would have been no need for the slain Christ. When Satan and his angels of darkness rebelled then sin was encompassed in a being. When Adam and Eve sinned in the Garden, they became sinners.
What was cursed as a result of sin? Sin itself was not cursed and punished, but the sinners. Satan and his Angels were cast out of Heaven. Adam and Eve were cursed and cast from the Garden. Sin cannot be punished only, sinners can be punished. Sin is not what is sent to Hell at the last day, sinners are.
Everyone would say they hate the sin of murder. We can discuss the fine points about why murder is wrong whether based on Scripture or not. However, when it comes down to a murder being committed murder is not what is on trial. The person who murdered is on trial. It is a person who will be punished for the sin of murder. He is a murderer; you cannot separate the murder from the murderer. Even after serving time in prison and “paying back society” he can be released but it will not take away the fact that he is a murderer. He can even repent, ask forgiveness and be forgiven by society yet he is still a murderer.
So where does this leave believers if God not only hates sin but also hates sinners? Does God love us or hate us? See even believers still sin so what is our hope? How do you reconcile that with God loved us while still sinners (Romans 5:8)?
