After having done all stand. I have gone through bouts of rebellion. It is satan working through your children and yes there is something deep inside of them that is wrong. What you have to remember is your love walk, read Luke 6:27-36. Also, sometimes we have been hurt so deeply that it makes it hard to walk the love walk but that is when we have to seek God for more grace and learn to not let unbelievers harshness get to us.

God told me for my situation about the story of the prodigal son Luke 15:11-31. My son wants to live the life of people in the world but I could not allow the things he wants to do in my home. So, I kept praying and asking God what to do and then I asked God to be the one to deal with what my son needed. God let me know to keep praying for him but to let him go the way he wants to go. God pulled me out of a life of sin and changed my ways. He can also do this with my son and yours. Ask God to let His will be done with your sons and when it is done don't fight it just pray for them. Pray them through and continue to walk in love. I am not telling you to tolerate their behavior because God is not pleased with what they are doing but what I am saying is to seek God for wisdom to know how to handle the situation.

Here is a portion of my devotional bible that introduces the book of Peter. This gave me wisdom I needed to get through:
Your attitude toward others represents Christ to them. Peter wants his readers to understand this point. Be as gentle as you can, especially when dealing with unbelievers. Forgive their harshness. Whether you're dealing with a hard boss, an unbelieving husband or someone else who sometimes makes life difficult, live for Christ and don't assert your own rights. Let the unbelievers see your good deeds and notice that you are different.God Bless!

Hi tina, welcome to our circle. first of all, Im happy to see you turn to prayer when you are unsure of what the world is doing. We hope to see you in the future too.

Caring Father,
tonight we ask that you take Tina in your arms and remind her that she is needed and loved. No matter what. PLease teach her to have patience and understanding towards her children who seem to be temporarily misguided.
God, help tinas children come together spiritually so they may soon hear Your Word. We Know anything is possible through You, and without knowing Jesus, simple tasks and situations will soon become unbearable. PLease show these kids how much their mother needs them in their lives.
*Amen*

Tina, when was the last time you REALLY sat down with no distractions and had a GOOD, long conversation with your kids? Probably a long time. Lately Ive learned that communicatin is the KEY to ANy relationship whether it is with God, a spouse, children, customers....etc.
I hope you can find a way to have a "talk" with your kids. Approach this with a smile, gentle words, and open arms. See if you can get them to "open up" a little about what is bothering them. This could be hard on you beacause they might say something you dont want to hear, maybe it is something from 15 years ago. It is important to get it out I think. Try to encourage them to speak to you though. Show concern and interest in their feelings towards you. Do this with an open mind so you can make right what is wrong, whatever it is.
God Bless You Tina, youre in our prayers
