The problem is that people reject and do let God rule their lives and people want to rule their own lives. Read his lyrics and see. He wants to be everything to everyone? That sounds like he wants to be god.
Only Jesus Christ can rightfully fill that role and only the Lord Jesus should.
Mental problems also root from spiritual attacks from Satan. Jesus has power over Satan. Jesus also has given His followers power over the enemy in Jesus’ name.
Dear Lord Jesus help people to see that only You Lord are our helper. Our Healer. Our Savior. Jesus please help the, see that You love them
