As you admit, he's being just like Dad was at his age. That being said, keep praying yourself. I have ZERO doubt that I only survived without getting killed doing crazy things during that time in my life because of the prayers of my parents.
The prayers of the righteous WILL NOT return void.
1 Timothy 1 15-17: Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners--of whom I am the worst.But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his unlimited patience as an example for those who would believe on him and receive eternal life.Now to the King eternal, immortal, invisible, the only God, be honor and glory for ever and ever. Amen.
Then stop it!
Your son is an adult. As a parent, your only job now is to love him, that's all. His personal life is no longer your business unless HE comes to YOU and asks for advice, help, etc. Until then, if anyone comes to you with tales of your son, stop them in midsentence and tell them, "My son's personal life is personal. If he wants me to know something, he will tell me. Thank you anyway."
All you've got to do is love your child.
Prayers are winging their way on you and your family's behalf.
Bump to the prayer lists.
