John 4:24 states that God is a spirit and therefore we must worship him in spirit.This therefore show to us that the spirit is an active being..able to perform.
The same way some people choose to serve God in spirit,some wicked ones have decide to torment others with their own spirit.This is what brings about spiritual problems.The bible say we wrestle no against flesh but principalities in high places..Most battles we fight today are spiritual and the strong in Spirit usually wins.
We nees to hold God tighter than ever so He can fight for us but as He hath promised that He will cause our oppresors to show us favour,So shall we overcome in spirit by the Grace of God.May He continue to fight our battles even when we are not strong enough.Awesome God
