The one thing that makes the war between good and evil so difficult is that those that are evil are not bound by any rules while the righteous are. Anything goes for the wicked; they can lie, cheat, steal, kill, fight dirty, and they do not hesitate to do all of these things in order to prevail. The righteous are bound by truth, justice, mercy, righteousness, and the fear of God to do what is right in spite of what the wicked do. God has given the righteous rules by which to engage the enemy, and every Christian needs to live by them or the cause of Christ suffers and souls are lost.
