Today, many churches have become personal businesses for inheritance wealth and franchises for theological opportunism, resulting in a weak doctrinal foundation, spiritual retardation, lack of biblical discernment, humanism, deism, doctrines of demons, and worldlinessthe conspicuous display of wealth. Whole denominations, even many where the gospel was once proclaimed clearly, have been left spiritually bankrupt because doctrines of demons and unbeliefs were tolerated. So-called men of God have become fame-obsessed celebrities, eager to please their congregations with human wisdom. There is a spirit behind every teaching. Why do people listen to irresponsible teaching that is spawned by seductive spirits? How to Test the Spirits and Understanding Seducing Spirits and Doctrines of Demons may be taken as a testament to that effect. This is clearly a last days occurrence within the church. It is every believers solemn duty to resist every attack on the truth by the master of the clever twist of the gospel, the Adversary; to abhor the very thought of falsehood; and to test the spirits to see whether they are from God.
