In summer 1548, as nearly as I can collect, the galleys in which they were confined returned to Scotland, and continued for a considerable time on the east coast, watching for English vessels. Knox’s health was now greatly impaired by the severity of his confinement, and he was seized with a fever, during which his life was despaired of by all in the ship.[93] But even in this state, his fortitude of mind remained unsubdued,[94] and he comforted his fellow‑prisoners with hopes of release. To their anxious desponding inquiries (natural to men in their situation), “if he thought they would ever obtain their liberty,” his uniform answer was, “God will deliver us to his glory, even in this life.” While they lay on the coast between Dundee and St Andrews, Mr (afterwards Sir) James Balfour, who was confined in the same ship with him, pointed to the spires of St Andrews, and asked him if he knew the place. “Yes,” {70} replied the sickly and emaciated captive, “I know it well; for I see the steeple of that place where God first opened my mouth in public to his glory; and I am fully persuaded, how weak soever I now appear, that I shall not depart this life, till that my tongue shall glorify his godly name in the same place.” This striking reply Sir James repeated, in the presence of a number of witnesses, many years before Knox returned to Scotland, and when there was very little prospect of his words being verified.[95] We must not, however, think that he possessed this tranquillity and elevation of mind, during the whole period of his imprisonment. When first thrown into fetters, insulted by his enemies, and deprived of all prospect of release, he was not a stranger to the anguish of despondency, so pathetically described by the royal psalmist of Israel.[96] He felt that conflict in his spirit, with which all good men are acquainted, and which becomes peculiarly sharp when aggravated by corporal affliction. But, having had recourse to prayer, the never‑failing refuge of the oppressed, he was relieved from all his fears, and, reposing upon the promise and the providence of the God whom he served, he attained to “the confidence and rejoicing of hope.” Those who wish for a more particular account of the state of his mind at this time, will find it in the notes, extracted from a rare work which he composed on prayer, and the chief materials of which were suggested by his own experience.[97]
