(Pro 2:17 KJV) Which forsaketh the guide of her youth, and forgetteth the covenant of her God.
As I read this today I was reminded that this is one of those verses in Proverbs that is not a free standing statement. It is an expansion of what has gone before. If you look back a verse it seems to be talking about people from outside the faith. The previous verse seems to indicate that these women are pagans who have tried to seduce the believer. Then you come to this verse.
One of the greatest dangers to believers is those who have once been part of the family of God and conveniently “forgets” (7911) the “covenant” (1285). It is easy to be deceived. Some people are masters of it. How many marriages have you seen where two people were joined together and one of them was playing the part in order to make the sale? Or you have others where the commitment was genuine but after a few years one decides that they don’t want it any more.
So? Read the next verse and you find that the outcome for the person who backslides, or if you are a Calvinist was never really saved. It talks about death and I guarantee that is not symbolic. Pray for people who are important to you and be as supportive as you can be.
