Christians who want to work must do it in the Holy Spirit. There is a difference between a working Christian and a saved. Good works are fruit we should produce. Work harder for God than any old master. We can do remarkable things if we allow the Holy Spirit to work through us. Exorcise evil. Baptize the innocent. We must know to discern Spirits and to speak. We have salvation, we have communion, we know who speaks from a foreign spirit or not. We must tell the difference between baptized or not
