’His office and his name agree;
A shepherd that and Shepard he.’
And many such entries as these occur in Thomas Boston’s golden journal: ‘I preached in Ps. xlii. 5, and mostly on my own account.’ Again: ’Meditating my sermon next day, I found advantage to my own soul, as also in delivering it on the Sabbath.’ And again: ’What good this preaching has done to others I know not, yet I think myself will not the worse of it.’
2. The preaching of that Fast-day was with great authority also. ’There was such power and authority in that sermon,’ reports one who was present, ‘that the like had seldom been seen or heard.’ Authority also was one of the well-remembered marks of our Lord’s preaching. And no wonder, considering who He was. But His ministers, if they are indeed His ministers, will be clothed by Him with something even of His supreme authority. ‘Conscience is an authority,’ says one of the most authoritative preachers that ever lived. ’The Bible is an authority; such is the Church; such is antiquity; such are the words of the wise; such are hereditary lessons; such are ethical truths; such are historical memories; such are legal saws and state maxims; such are proverbs; such are sentiments, presages, and prepossessions.’ Now, the well-equipped preacher will from time to time plant his pulpit on all those kinds of authority, as this kind is now pertinent and then that, and will, with such a variety and accumulation of authority, preach to his people. Thomas Boston preached at a certain place with such pertinence and with such authority that it was complained of him by one of themselves that he ‘terrified even the godly.’ Let all our young preachers who would to old age continue to preach with interest, with pertinence, and with terrifying authority, among other things have by heart The Memoirs of Thomas Boston, ‘that truly great divine.’
