For, simple as the suggestion may be; lacking all flavour of the extraordinary as it does; without novelty and confessedly old-fashioned; we have but this to commend to all who waver and doubt, to all whose voices falter as they seek to utter the mighty affirmations of the Gospel:--That the way to win again the old assurance is to come back to the source of their sublime vocation, determined, whatever may befall, there to abide all the long and trying day. "Reach hither thy finger," He said to the doubter whose faith had well-nigh died for loss of a few days' open vision, "Reach hither thy finger and behold My hands and reach hither thy hand and thrust it into My side and be not faithless but believing." The spirit of St. Thomas comes upon us all at times, perhaps more often in youth than age. Occasionally it comes uninvited; sometimes, alas! we open the door and bid it enter. There is but one way of escaping this spirit, and it is recorded in this old history. Surely for doubting souls in all ages was this experience of Thomas written down! The way of certainty is the way of the extended hand. Ultimately the preacher's faith depends upon the use he makes of his own spiritual opportunities. "If any man will do His will he shall know of the doctrine whether it be of God." There is an intimate connection between intellectual results and moral and spiritual conditions. The surrender of the will to God is always followed by an increase of spiritual intelligence. That this is true we have seen proved unnumbered times as lowly piety has revealed sublimities of faith and trust. Spiritual things are, and must be, spiritually discerned. And this is not so hard to understand as may appear. A life surrendered to the will of God is of all lives the most peaceful and composed. It is lived in an atmosphere of repose. In such an atmosphere the mind has an opportunity of looking upon the great spiritual mysteries in the light proper to their contemplation and consideration. It is a life of good works too, and good works tend to establish the gospel by which they were inspired. It would not be easy--we had almost said it would be impossible--to find a man engaged in hard and constant toil for Jesus Christ who would complain that he suffers from doubt as to the truth of the faith he serves. Unbelief is not unfrequently the penalty of indolence. It might in many instances be found possible to trace the doubts of men to their slackness in the service of God.
