This video made me cry also.
For the young babes in Christ and even those who may have been a little confused, the part in the very end where the man playing Christ is fighting to hold back the demons, please note it has nothing to do with Christ's power over demons nor comparison to the devil's power. It is merely the person's will to choose Jesus and to cry out to Him in prayer. So in the end the fight between the devil and GOD is over your mind, the believer. Your mind is where you think of your choices, to follow GOD or not for example.
GOD has absolute power over all, but as that fight in the end between Christ and the demons, it comes down to the person's choice.
James 2:18-20
18Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
19Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
20But wilt thou know, O vain man, that faith without works is dead?
