If you are wanting to avoid spiritual warfare...do nothing.  Because when Paul describes how to put on spiritual armor he's talking to people who are actually going into battle.  And the people who are really ready to go into battle better put on the armor.  

We have the wrong idea if we think that when we are doing something for God it should be easy.  Just ask Nehemiah.
