fighting, strive, striving

Dictionary of Biblical Words:

is with wicked spirits in heavenly placer (Eph. 6). It is not with the flesh which is to be reckoned dead, nor with the world to which we are crucified, but with Satan and his angels, who do all they can to prevent us enjoying our spiritual blessings, or making them known to others. For this conflict we require the complete armor described in Eph. 6 The warfare is purely spiritual, but its character is aggressive, not merely defensive. See Armor.L
