A dog returns to his vomit...

"As a dog returns to its vomit, so a fool repeats his foolishness." Proverbs 26:11

"For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and overcome, the latter end is worse for them than the beginning.

For it would have been better for them not to have known the way of righteousness, than having known it, to turn from the holy commandment delivered to them. But it has happened to them according to the true proverb: "A dog returns to his own vomit," and, "a sow, having washed, to her wallowing in the mire."  2 Peter 2:20-22

A fool lacks moral fiber and discipline. A fool lacks integrity, that "doing what is right even when no one is looking." (Completely forgetting that the Lord is indeed looking). God does not want us to be fools.  He provides us the Holy Spirit to teach us, to guide us in the way of righteousness.  It is a sickening thought to think of a dog returning to eat what he just barfed up. Going back into sin, failing to repent and repeat the same sins - these things should be as repulsive to us as the thought of eating vomit. Being overcome with sin, being unrepentant and unholy, leads to a worse end than the beginning. That should worry us! 

The Father has set a lavish feast before us - why eat vomit?  He's washed us and clothed us in Christ, why go roll in the mud?
