As a parent, you have spiritual authority over your child. It doesn't make any difference if your child rebels. I know because I went through this for a time with my daughter.

God dealt with me strongly about this one day. He said:
Son, I want you to understand something: There is no power on earth greater than My power—no power!

Your daughter doesn't have the power and the faith to get out of the trouble she is in. It will have to be done by your faith in Me.

I can set her completely free through your faith, but your faith concerning her has been wavering a little. You have started wondering about when I am going to do it. That is none of your business. I don't need your help. All I need is your faith. I have to have your faith before My power is even available to move on your child.

Every time—not just part of the time, but every time—your faith wavers, it cuts off My power from dealing with her. You're her father, and your unwavering faith will bring My power out of heaven and upon her life to set her free.

But your faith wavers from time to time concerning her complete freedom. Sometimes you even wonder if I am going to do it. When you waver, My power stops.
That's the reason Hebrews 11:6 says that without faith it is impossible to please God. You can't please God without faith. You must have faith.

He wants you to recognize Him as your number one God. He wants you to know that He will work in your life. But to know that, you must spend time with Him and get to know Him.

If you will stand with an unwavering, steadfast faith, you can keep your child out of the hands of the devil. If your child is away from God now, you can bring him back to God.

If you will spend time worshipping the Lord through faith, the devil can't destroy your child. There is no way the devil can destroy any of your children if you will follow the Lord and listen to His instructions.
