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. God wants us to understand this so that we ll avoid the deathtrap of sin. It is wisdom to learn this, that wisdom that James described, which comes from above and which God gives generously. Please take note of this. A similar process takes place in any sin, ranging from fraud and slander to murder and rape.
