If you have been a Christian for longer than a day you have either heard about or engaged in spiritual warfare. We have an enemy who is out to get us, this we know.
We have armor, we have weapons, we are in a battle.
Life is not easy. Just about the time we think we have it all figured out, something hard hits us and down we go. We get up, check our armer, sharpen our weapons, and stand. We have practiced this over and over. We have memorized important scriptures on spiritual warfare and we use them.
