Peter's deliverance was now complete. The angel conducted him through one street to assure him that he was really free and secure him from bewilderment, and then departed. The Apostle thereupon sought out the well-known centre of Christian worship, "the house of Mary the mother of John, whose surname was Mark," where stood the upper chamber, honoured as no other upper chamber had ever been. There he made known his escape, and then retired to some secret place where Herod could not find him, remaining there concealed till Herod was dead and direct Roman law and authority were once more in operation at Jerusalem.[101] There are two or three details in this narrative that are deserving of special notice, as showing that St. Luke received the story most probably from St. Peter himself. These touches are expressions of St. Peter's inner thoughts, which could have been known only to St. Peter, and must have been derived from him. Thus we are told about his state of mind when the angel appeared: "He wist not that it was true which was done by the angel, but thought he saw a vision." Again, after his deliverance, we are told of the thoughts which passed through his mind, the words which rose to his lips when he found himself once again a free man: "When Peter was come to himself, he said, Now I know of a truth that the Lord hath sent forth His angel, and delivered me out of the hand of Herod, and from all the expectation of the people of the Jews." While, again, how true to life and to the female nature is the incident of the damsel Rhoda! She came across the courtyard to hearken and see who was knocking at the outer gate at that late hour: "When she knew Peter's voice, she opened not the gate for joy, but ran in and told that Peter stood before the gate." We behold the impulsiveness of the maid. She quite forgot the Apostle's knocking at the gate in her eager desire to convey the news to his friends. And, again, how true to nature their scepticism! They were gathered praying for Peter's release, but so little did they expect an answer to their prayers that, when the answer does come, and in the precise way that they were asking for it and longing for it, they are astonished, and tell the maid-servant who bore the tidings, "Thou art mad." We pray as the primitive Church did, and that constantly; but is it not with us as with them? We pray indeed, but we do not expect our prayers to be answered, and therefore we do not profit by them as we might. [101] There is an ancient tradition that our Lord bade the apostles remain twelve years in Jerusalem before they dispersed to preach the gospel all the world over (Eusebius, _H. E._, V., xviii.). Some think that the famine and persecution which now happened may have been the occasion of their dispersion.
