"As a dog returneth to his vomit, so a fool returneth to his folly." Proverbs 26:11
The bigger picture that the verse is painting is one that shows how repulsive it is for us to continue to go back to the same sins over and over again. It didn't "agree" with our spirits to begin with, and it won't again. For you to continue to go back to your "folly" (sin) is degrading to the person God created you to be.
God has called you to live an abundant life. Not a life of bondage continually returning to those things that pull you further down and away from Him. But I have good news, you don't have to be like a fool. You don't have to keep returning to the same pit of "vomit". You can live in victory. You can live in abundance of peace, joy and grace. How? Through Jesus. He overcame the power of sin. He got the victory over those things that would keep you going back and forth to old sinful habits and practices. He provides you His power and strength to resist and to stand firm and overcome. Through Him you are more than a conqueror over those things that would entice you to return to them.
Don't give in! Don't go back! Don't return to those old habits, old ways and old sins! Don't be like a dog returning to his own vomit. Be the wise, victorious, overcoming person that you are through Jesus.
Have a great day. Going back again to those sins that have had you in bondage in the past is like a dog returning to its vomit.
