My dad also knew when he wanted to go to Jesus when he was ill and he did do very peacefully. I pray that your father go to be with his Lord when his time comes. I pray that your father is kept free from pain until that time comes. Also Lord please bring Tyler back to his parents who will love him and care for him.. I bind all the governmental red tape that may be keeping him there. Lord please send your angels to bring Tyler home Amen. I will continue to pray for your situation.
