Sin to a non believer taste like eating a sweet cake but to a believer taste like eating rotten meat.
The non believer will enjoy his meal of sin but the believers meal of sin will make him sick to his stomach.
In time the non believers meal will kill him because he consumed too much.
The believer will live because he did not consume much of what made him sick.
For it was the sweetness that killed the non believer but it was the bitterness that saved the believer.
