For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. (Ephesian 6:12)
We must fight the powers of this dark world (here on the ground) so that the heavenly realms are backed by good over evil....correct?
So it is up to every Christian to stay the course and follow Christ, not be of this world...
