'Conflict' in the Bible

And if Satan really has engaged in fierce conflict with himself, how shall his kingdom stand?--because you say that I expel demons by the power of Baal-zebul.

For ours is not a conflict with mere flesh and blood, but with the despotisms, the empires, the forces that control and govern this dark world--the spiritual hosts of evil arrayed against us in the heavenly warfare.

maintaining, as you do, the same kind of conflict that you once saw in me and which you still hear that I am engaged in.

But continually recall to mind the days now past, when on being first enlightened you went through a great conflict and many sufferings.
