Lord remove that depression this person suffers from for good. Bring his loved ones back into their life and heal anything that may stand in its way. Have your perfect will be done in their life and their situation, I pray this in Jesus name, amen.
Please try to get and read this book, it has helped many as it did to me too. "Hinds' Feet on High Places" by: Hannah Hurnard it will help you understand why we go through our highs and lows in our live's and how God always love us and is our only helper during these times. I highly recommended for every Christian to read.
