Satan is ego. We all have access to that. We are NOT satan. We have control OVER our temptations and desires if we are stable and balanced people.
Satan is like pain. We need to know it is there so we try to avoid it by being healthy.
Mentally healthy means striving to stay away from that which causes mental illness. EXCESS for one. Lust, anger, jealousy greed, to name a few. We need to overcome those emotions and strive to be above such childish and petty responses. SO TRUMP? He is an example of what not to be.
