Mark 16:17-18

17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;

18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick and they shall recover.

John 14:12

12 Verily, Verily I say unto you, He that believeth on me, the works that I do shall he do also; and greater works then these shall he do; because I go unto my Father.
