Paul is working hard to prepare us for that war. Four times within there he talks about standing firm, stand against, withstand. He is telling us that if we stand firm in Christ, then Christ will be with us because we are standing up for Christ. And know only through Jesus Christ that we can defeat this enemy. That is why He provides these resources for us. We cannot do it on our own. Again, this is a spiritual war. And so only through His strength and His power will we overcome it.
