We all have issues in our families that are hard to deal with. Each of my children has a mess of their own, and I could run myself ragged trying to fix them, but I don't. They were created by our loving Father and I have left that responsibility to Him. He gave me to them to offer love, guidance, and emotional support, but they must seek Him as I do for things that are beyond their ability to repair. Even our prodigal son knows this and when he's down on himself, he will refer back to his upbringing and is remorseful for not following the lessons he was taught. We must be confident in God's ability to see our children through their difficulties. The worse thing you could do is to jump in and try to fix it, you are not God! However, we are responsible to intercede for them, especially when we know they aren't doing it for themselves. My point is, we must leave it to God to help our children, He loves them well beyond our love for them.
Train up a child in the way he should go; even when he is old he will not depart from it. Proverbs 22:6
