As believers, we must know that we are engaged in the fiercest of all battles. We are not doing battles with flesh and blood. That means, our battles and spiritual struggles is not against fellow believers. Our battle is with the god of this world - Satan, and is directed against the evil spirits behind every wrong action that manifests in our lives. Since Satan seems to be more knowledgeable and powerful than we are, God has provided a way for us to escape, conquer, and defeat him in every spiritual battle, and that way is through our putting on of the whole armour He has provided. In this book, we shall examine these armours closely, and also fully understand how not to only resist Satan, but how to go on the attack and win our spiritual battles.
