In an age when science seems so sure of itself, socialists are considered to be only concerned about your welfare, and Islam is advertised as a "peaceful religion, it seems prudent to give readers an opportunity to take a closer look as these seemingly benign descriptions. There are many enemies attacking Christianity today--from within and from without. This book addresses, what in my opinion are, the three most insidious and harmful currently on the scene: Secular Humanism, True socialism, and Islam. When a nation is at war, the prudent thing to do is to learn as much about the enemy as you can. We, as Christian Soldiers, are in a war; regardless whether everyone realizes it or will admit it. Know your enemy! We are not at the mercy of science, humanism, or Islam, unless we remain unwilling and ill equipped to positively and aggressively respond. Herein is information that will hopefully give confidence that the battle is not unwinnable, and that will spur the reader on to further study. This book aims to be a companion to Paul's advice in Ephesians 6:10-18.
