John 14:12

Verily, verily, I say unto you, he that believeth on me,.... Having mentioned his miracles as proofs of his deity, he assures his disciples, in order to comfort them under the loss of his bodily presence, that they should do the same, and greater works; for we are not to understand these words of everyone that believes in Christ, of every private believer in him, but only of the apostles, and each of them, that were true believers in him: to whom he says,the works that I do shall he do also; he shall raise the dead, heal all manner of diseases, and cast out devils; things which Christ gave his apostles power to do, when he first gave them a commission to preach the Gospel, and when he renewed and enlarged it: and which they did perform, not in their own name, and by their own power, but in the name, and by the power of Christ:and greater works than these shall he do; meaning, not greater in nature and kind, but more in number; for the apostles, in a long series of time, and course of years, went about preaching the Gospel, not in Judea only, but in all the world; "God also bearing them witness with signs and wonders, and divers miracles and gifts of the Holy Ghost", Heb 2:4, wherever they went: though perhaps by these greater works may be meant the many instances of conversion, which the apostles were instrumental in, and which were more in number than those which were under our Lord's personal ministry: besides, the conversion of a sinner is a greater work than any of the miracles of raising the dead, &c.
