To use Paul's analogy, our spiritual diet must not be a mixture of true and false doctrines. In this area of life, a mixture produces nothing good (James 3:11-12). We must make every effort to separate the true food from the false if we are to grow and qualify for the Kingdom of God. This is a responsibility that falls on each of us—we cannot leave it to others! We must acknowledge the source of the false teaching—Satan, his demons, and his false ministers—to truly appreciate the seriousness of heresy.
Heresy is not always easily detected because Satan usually camouflages the lie with a large measure of truth. He is a master of deceit. Because the world is so ignorant of God, Satan can tell them virtually anything, and they will believe it. But with us he generally does not directly challenge or obviously and blatantly misquote Scripture. His confrontation with Jesus, beginning in Matthew 4:1, is a classic example. He subtly twists the intent of a scripture to bend it into a wrong application or understanding. At other times, he will appeal to our vanity to get us to react to his suggestions without thinking.
