After his comments about Trump, I'd say he probably is going through a spiritual crisis.  He's clearly confused and has a lot of ideas bouncing around in his head.  Not knowing anything about him (never listened to a song of his for example), I wouldn't have the first idea what's happening.  However, it could be anything from an emergence/intensification of mental illnesses to a genuine conversion to Christ.  I pray for him that he may find the grace, peace, and true joy that only Jesus can bring.
