Now they have known, &c.— "These men are fully persuaded, that the commission whereby I act, the doctrine of salvation which I teach, the miracles which I perform, and the authority with which I am clothed, as Mediator, are all derived from thee. In this indeedthey have acted upon the surest evidence; for I have revealed to them those mysteries of the kingdom, relating to my person, offices, and benefits, which thou hast authorized me to make known for their instruction and edification; and they, under my grace, have cordially entertained them with faith and love, and accordingly have been well assured in their own minds and consciences, that I, as a divine Person, came into this world from thee; (ch. John 16:30.) and they have savingly believed in me as the true Messiah whom thou hast sent."
