In this sermon, the preacher discusses the conflict between the church, which is indwelt by the Spirit of God, and the world, which is indwelt by the Spirit of error. The preacher emphasizes the importance of knowing how to test the spirits to determine if someone is speaking from God or not. The first guideline given is to see if the person confesses Jesus as having come in the flesh. This is a crucial factor in discerning if someone is speaking from God or the devil. The preacher shares an example of testing this guideline by visiting the Unification Church and asking them about their belief in Jesus as the Messiah.

Thomas Brooks delivers a powerful sermon on the dangers of covetousness, labeling it as explicit idolatry and a pervasive sin that has infected all levels of society. He emphasizes that a covetous person places their love and trust in worldly riches, neglecting God and spiritual matters, which ultimately leads to ruin. Brooks illustrates this with a poignant story of a greedy banker who, on his deathbed, bequeaths his soul and those of others to the devil due to their failure to recognize the spiritual dangers of their worldly pursuits. The sermon serves as a stark reminder of the consequences of prioritizing material wealth over spiritual well-being.

John Gill emphasizes the distinction between true believers and false prophets, who are characterized by their worldly nature and teachings. He explains that these false teachers, influenced by the spirit of antichrist, promote doctrines that align with worldly desires and human wisdom, appealing to the carnal minds of their followers. Their messages, which often deny the necessity of grace and promote justification by works, are well-received by the unregenerate, highlighting the danger of their influence. Gill warns that the popularity of such teachings among the masses should not surprise true believers, as both the preachers and their audience are aligned with the world.
