The Prosperity Gospel is a clever scheme that draws on a person's desire for material gain instead of a desire to seek God. It presents a false gospel that is contrary to the Gospel of Christ---which makes it a doctrine of demons.
Why Should Christians Belong to a Church?
Christ instituted the Church as His own precious possession to fulfill the Great Commission by declaring His Gospel to a world that is lost in spiritual darkness. The members of His Church are not meant to be a closed society concerned only with the needs of the congregation. They were chosen as a Royal Priesthood to be the lights of the world that engages the Kingdom of Darkness which opposes the rule and reign of God in this world.
