There is not the slightest suggestion upon record that Christ set any limit to this charge which He gave His disciples.

On the contrary, there are not lacking hints that He looked for the possession and exercise of this power wherever His spirit breathed in men.
Even if the concluding paragraph of St.Mark's Gospel were a later appendix, it may none the less have been a faithful echo of words of the Master, as it certainly is a trustworthy record of the belief of the early Christians as to the thought of Jesus concerning His followers.
In that interesting passage, Jesus, after His death, appeared to the eleven, and formally commissioned them, again, to take up His work in the world; bidding them, "Go ye into all the world and preach the gospel to every creature." "And these signs," He tells them, "shall follow them that believe"-- not the apostles only, but "them that believe," without limit of time; "in My name they shall cast out devils...

they shall lay hands on the sick and they shall recover." The concluding discourse to the disciples, recorded in the Gospel according to St.John, affirms the same expectation on the part of Jesus; emphasizing it in His solemn way: "Verily, verily, I say unto you, He that believeth on Me, the works that I do shall he do also; and greater works than these shall he do." APPENDIX F Few will deny that an intelligence apart from man formed and governs the spiritual universe and man; and this intelligence is the eternal Mind, and neither matter nor man created this intelligence and divine Principle; nor can this Principle produce aught unlike itself.

All that we term sin, sickness, and death is comprised in the belief of matter.
The realm of the real is spiritual; the opposite of Spirit is matter; and the opposite of the real is unreal or material.

Matter is an error of statement, for there is no matter.
