Jesus said (John 14:12), "He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father." This is a significant declaration that the truths of Christian healing belong to every age and may be practiced by everyone who is sincerely seeking the truth. There was no monopoly in the thought of Jesus. Inclusiveness, not exclusiveness, characterized every act.
In the Bible we see evidences that the impartial nature of God was understood by many. When Moses was informed that two men, Eldad and Medad, were prophesying in the camp instead of joining the group around the tabernacle, Joshua asked Moses to forbid them. Moses replied (Num. 11:29), "Enviest thou for my sake?" He then added that he wished that all would prophesy.
The Gospel of Mark records that the disciples saw someone casting out devils in Jesus' name, and that, since he did not belong to their circle, they forbade him. Unhesitatingly the Master replied (9:39), "Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me."
