My mind has been swirling since I read your post on Pep's thread today.
In those words he is saying something very important to people who need to be healed: do not make any provision to go back on what you have done. Many people fail right here. Go home and pour out the alcohol! Go home and get rid of the drugs! Burn your bridges behind you. Say no to the friends who have been luring you on into evil. You will probably find that some of them will come back with you. Burn your bridges. Cut off any possibility of going back. Let somebody know the new stand you have taken so that he will help hold you to it. Burn your bridges, is what Jesus is saying. That is so important. Many a person has really been touched by God, delivered from some inner attitude, a bitter spirit or whatever, but then he has allowed the past to come back in again and he finds himself back where he was. Our Lord knows what he is talking about -- "take up your bed."
This speaks to me as something the WS needs to do, ie NC. The OP luring the WS back into evil, burning bridges is the NC letter, changing all methods of earlier contact.
What you need to know is, where is God moving in your life, and then work with him. Be his instrument. Allow it to endure. The only thing that lasts, that gives significance to life -- and every one of us wants to be significant -- is to be in line with what God does. Only God's work will last. All that men do will fall away to nothing. Even though it be religious work it will be nothing -- trash, crap, burned by fire. What God does is what will last.
Trust in God, not in man. Do you want to be healed? Hmmm.. good question to ask not just for the WS but for the enabling BS.
I need to think on this some more. I just wanted to thank you and tell you what an impact it had on me. I went to the link and printed out the entire sermon to read.
