Jude 9 shows that the spiritual war between God & Satan takes place on this earth and in us. It's easy to think about war as far away and foreign, but we truthfully acknowledge war's nearness in the Lord's prayer - "deliver us from evil." The "horizontal" concept of fighting in spiritual warfare means to rebuke the darkness we see around us, day to day. This is the way to defeat Satan.
I've been praying for spiritual warfare all this time without realizing it. I haven't been asking for evils drawn out, but rather, light to be drawn in. My personal prayers for those around me, and within myself, are good vs. evil prayers.
