We must be ready to give a defense. In order to defend Christ, we first must acknowledge that an attacker threatens. The battlefield upon which we make our defense is not a fanciful gaming board or a plastic-soldier playground. Our feet have been planted in the bloodiest trench the world has ever known. The devil, our adversary, walks about like a roaring lion, seeking whom he may devour (1 Peter 5:8). He sinks his teeth into the world through atheism, evolution, egotism, materialism, selfishness, and a host of other vicious vices. Once his teeth are embedded firmly, he rips and tears human souls away from their Creator, leaving fang-holes that fester and infect everything around them. He is real, he is malicious, and he is determined. Yet, fortunately, we are not ignorant of his devices. We have been placed on the defensive by the supreme menace of mankind. As we defend what is right and good, we offend all that is wrong and evil. Until we recognized that Satan and his cohorts have initiated a battle that jeopardizes the souls of all mankind, we never will be ready, nor able, to defend the Lord’s cause.
