This passage paints vividly the discouragements which are apt to dog all good work, and the courage which refuses to be discouraged, and conquers by bold persistence. The first verse (v. 9) may stand as a summary of the whole, though it refers to the preceding, not to the following, verses. The true way to meet opposition is twofold--prayer and prudent watchfulness. 'Pray to God, and keep your powder dry,' is not a bad compendium of the duty of a Christian soldier. The union of appeal to God with the full use of common sense, watchfulness, and prudence, would dissipate many hindrances to successful service. I. In verses 10-12 Nehemiah tells, in his simple way, of the difficulties from three several quarters which threatened to stop his work. He had trouble from the workmen, from the enemies, and from the mass of Jews not resident in Jerusalem. The enthusiasm of the builders had cooled, and the magnitude of their task began to frighten them. Verse 6 tells us that the wall was completed 'unto the half of it'; that is, to one-half the height, and half-way through is just the critical time in all protracted work. The fervour of beginning has passed; the animation from seeing the end at hand has not sprung up. There is a dreary stretch in the centre, where it takes much faith and self-command to plod on unfainting. Half-way to Australia from England is the region of sickening calms. It is easier to work in the fresh morning or in the cool evening than at midday. So in every great movement there are short-winded people who sit down and pant very soon, and their prudence croaks out undeniable facts. No doubt strength does become exhausted; no doubt there is 'much rubbish' (literally 'dust'). What then? The conclusion drawn is not so unquestionable as the premises. 'We cannot build the wall' Why not? Have you not built half of it? And was not the first half more embarrassed by rubbish than the second will be? It is a great piece of Christian duty to recognise difficulties, and not be cowed by them. The true inference from the facts would have been, 'so that we must put all our strength into the work, and trust in our God to help us.' We may not be responsible for discouragements suggesting themselves, but we are responsible for letting them become dissuasives. Our one question should be, Has God appointed the work? If so, it has to be done, however little our strength, and however mountainous the accumulations of rubbish.
