Your son will be in my prayers. I think God has a special place in his heart for teens. Paul says in 1 Corinthians 13:11
When I was a child I spake as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. I lost my son at age 16. Show him love and let him see God working in your life. He will come around, God will draw him in.
May the joy of the Lord be your strength. God bless you sister in Christ !
