The person then begins to creep toward the edge of immorality. Everyone else does this, and a host of other rationalizations. Then the tempted person, who is quite relishing in his decline, begins to set dates. Enticement nurtures the forming sin. There are many other intermediate steps before the murder of the marriage, but it is clearly on the brink.
Temptation grows and becomes embedded.
It is tougher and tougher to shed, even if the tempted wanted to. Finally, an act is done, a marriage destroyed, a home and many other lives wrecked because this sin was not nipped in the bud. Sin is birthed, and finally it grows and leads to death. Marriages can die from sin just as surely as our bodies suffer physical death. It started small, perhaps even in playful innocence, but it was not snuffed out and led to death.
