And there are some of us who, in like manner, spoil all the good that we could get out of a wise retrospect, by only looking back in such a fashion as to feed a sentimental melancholy, which is, perhaps, the most profitless of all the ways of looking backwards. Now here are the two points, in this verse of my text, which would put all these blunders and all others right, telling us what we should chiefly think about when we look back, and from what point of view the retrospect of the past must be taken in order that it should be salutary. 'Thou shalt remember all the way by which the Lord thy God hath led thee.' Let memory work under the distinct recognition of divine guidance in every part of the past. That is the _first_ condition of making the retrospect blessed. 'To humble thee and to prove thee, and to know what was in thine heart, whether thou wouldest keep His commandments, or no'; let us look back with a clear recognition of the fact that the use of life is to test, and reveal, and to make, character. This world, and all its outward engagements, duties, and occupations, is but a scaffolding, on which the builders may stand to rear the true temple, and when the building is reared you may do what you like with the scaffolding. So we have to look back on life from this point of view, that its joys and sorrows, its ups and downs, its work and repose, the vicissitudes and sometimes contrariety of its circumstances and conditions, are all for the purpose of making _us_, and of making plain to ourselves, what we are. 'To humble thee,' that is, to knock the self-confidence out of us, and to bring us to say: 'I am nothing and Thou art everything; I myself am a poor weak rag of a creature that needs Thy hand to stiffen me, or I shall not be able to resist or to do.' That is one main lesson that life is meant to teach us. Whoever has learnt to say by reason of the battering and shocks of time, by reason of sorrows and failures, by reason of joys, too, and fruition,--'Lord, I come to Thee as depending upon Thee for everything,' has wrung its supreme good out of life, and has fulfilled the purpose of the Father, who has led us all these years, to humble us into the wholesome diffidence that says: 'Not in myself, but in Thee are all my strength and my hope.' I need not do more than remind you of the other cognate purposes which are suggested here. Life is meant, not only to bring us to humble self-distrust, as a step towards devout dependence on God, but also to reveal us to ourselves; for we only know what we are by reflecting on what we have done, and the only path by which self-knowledge can be attained is the path of observant recollection of our conduct in daily life. Another purpose for which the whole panorama of life is made to pass before us, and for which all the gymnastic of life exercises us, is that we may be made submissive to the great Will, and may keep His commandments.
