I thought about how many times we look at a perceived "enemy" that's actually ourselves.
For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world. 1 John 2:16
All those things listed above come from within us, yet we're so quick to blame other people or good old Satan for battles we're really fighting within ourselves. I've said before that sometimes I make the devil's job way too easy and give him too much credit, because my worst enemy is just my flesh. It's my desire to stop butting my head against my reflection and focus on the real enemy, and the battle going on around me, rather than within me. Sometimes I just need a cow to remind me of that.
