He does this to try to hinder the work of God on earth. He encourages Christians to ignore the Word and accept false teaching so that they will revert to their former manner of life. He tempts the believer with an improper emphasis on details of life such as money, success, social life, pleasure, loved ones, health, sex, materialistic things, or status symbols. The mature believer knows that his happiness is not derived from these things, so he is not a slave to them. The novice Christian, however, may try to gain happiness from such things, and this will distract him from the Word of God.
False teaching is a part of Satan's strategy.
They court believers. They appeal to human pride. They promote idolatry because it is a quick way to demon influence. They promote legalism. The false teachers will continue to operate throughout Satan's rule on earth.
