The casting out of demons testifies to the future casting out of Satan and his armies into the lake of fire. The Church, by this power, asserts Jesus to be the world’s true King, and Satan to be a deposed prince.
The speaking with tongues testifies to the universality of Christ’s redemption, not being confined to one nation, and to the future restitution of a divided humanity. The taking up of serpents testifies that in Christ’s kingdom even animals will lose their ferocity (Isa. 11: 6–8).
Drinking poison without taking harm. This testifies to the power by which Christ will completely eliminate the curse out of this earth. He will liberate Nature from her thraldom. All hurtful properties will be taken away.
The healing of the sick. The first fruits of that power by which death itself shall be destroyed by the Prince of Life. - MAX I. REICH
