Let the Bible principles guide you rather than listening to Satan. Realize that sin destroys and only Christ can save. Satan blinds people to the eternal nature of their souls. He tells people that the soul is the breath of life and that when we die that the soul ceases to exist. This is absurd.
Bodies decay but souls live on, awaiting the resurrection and the judgment day.
Satan blinds people to the one church of the Bible. Denominationalism and the church differs as to origin, foundation, membership, head, and plan of salvation. These good people have been blinded by Satan. Men have various ecclesiastical governments in their churches all of which are contrary to the church that Jesus built. Satan makes them think that any thing is all right.
