Very interesting point Seth. I have worked with families and children for many years now – both secular and spiritual. In the secular world, it is called by many names, depression, psychosis, etc…I had many a conflict with Mental Health officials about “causes” of why people do things. In the church, we have now accepted that sin, demonic activities are now called problems, or hang-ups. What I have noticed in may years loving Jesus is that we do have a sin problem, and yes, Jesus had demons to deal with, and so do we. Interesting, I never heard Jesus say to the different people he healed or delivered “It is okay, you were hurt or abused as a child, your mania, depression, or sin is just because of what you went through.” He spoke his word and delivered them. We must do also, speak God’s word against sin and demonic activity. Yes, I do believe there are chemical issues with some, but isn’t that possibly a spirit of infirmity? I have only seen that Jesus works, not any pill, or counselor(although God allows us in his mercy and grace to use these). Jesus is truly the answer for the world today. Let us not become so confomred to the ideas around us, that we accept people and their issues as something to live with…let us speak Jesus’ words…maybe this young man would have been set free.
