Verily, he that believeth on me, &c. Having mentioned his miracles, Jesus proceeds to promise, that he would endow his apostles with a power of performing even greater wonders than any they had ever seen him do. He made them this promise to animate them in their work, and that they might not despond in his absence, when they received such tokens of his remembering them, and such proofs of his power with the Father. “How fully,” says Macknight, “Jesus performed this promise, is plain from the history of the Acts throughout, particularly John 5:15, where we find, that the very shadow of Peter, passing by, cured the sick on whom it fell, and who were laid in the streets for that purpose: also from John 19:12, which informs us, that handkerchiefs and aprons, which had touched the body of Paul, being applied to the sick and possessed, banished both the diseases and the devils. Nor should we, on this occasion, forget the gift of languages bestowed on the apostles, and which they were enabled to communicate unto others. Yet if these miracles are not thought to show greater power than Christ's, we may refer the greatness, whereof he speaks, to the effect which they were to produce on the minds of men. For, in that respect, the apostles' miracles were vastly superior to Christ's; converting more people in one day, than was done by all the miracles that Jesus performed during the course of his ministry. They converted thousands at once, made the gospel to fly like lightning through the world, and beat down every thing that stood in opposition to the faith of their Master.” And whatsoever ye shall ask Under the influence of my Spirit, and subservient to the great end of your life and ministry; that will I do Although the promise is here conceived in general terms, yet the subject treated of directs us to understand it especially of miracles wrought in confirmation of the gospel; that the Father may be glorified in the Son Who, when he is ascended up to heaven, will from thence be able to hear and answer prayer, and, even in his most exalted state, will continue to act with that faithful regard to his Father's honour, which he has shown in his humiliation on earth. If ye ask any thing, &c. I repeat it, for the encouragement of your faith and hope, that I will be as affectionate and constant a friend to you in heaven, as I have ever been on earth.
