Proverbs 18:21 NKJV
Death and life are in the power of the tongue, And those who love it will eat its fruit.
Speak life and Gods word over him and his situation. Remember also we have free will and so does he, I dont say that to be coy but just as awareness.
I reccomended Ecc 3 earlier to a friend read it and be encouraged. Jesus is lord in all seasons. Matthew 18:19-20 Ill be praying with you.
