I am sure that, under God, the great remedy for social evils lies mainly here, that the bulk of professing Christians shall recognise and discharge their responsibilities. It is not ministers, city missionaries, Bible-women, or any other paid people that can do the work. It is by Christian men and by Christian women, and, if I might use a very vulgar distinction which has a meaning in the present connection, very specially by Christian ladies, taking their part in the work amongst the degraded and the outcasts, that our sorest difficulties and problems will be solved. If a church does not face these, well, all I can say is, its light will go out; and the sooner the better. 'If thou forbear to deliver them that are appointed to death, and say, Behold! I knew it not, shall not He that weigheth the hearts consider it, and shall He not render to every man according to his work?' And, on the other hand, there are no blessings more rich, select, sweet, and abiding, than are to be found in sharing the sorrow of the Man of Sorrows, and carrying the message of His pity and His redemption to an outcast world. 'If thou draw out thy soul to the hungry, and satisfy the afflicted soul, the Lord shall satisfy thy soul; and thou shalt be as a watered garden, and as a spring of water whose waters fail not.' 'OVER AGAINST HIS HOUSE' 'The priests repaired every one over against his house.'--NEH. iii. 28. The condition of our great cities has lately been forced upon public attention, and all kinds of men have been offering their panaceas. I am not about to enter upon that discussion, but I am glad to seize the opportunity of saying one or two things which I think very much need to be said to individual Christian people about their duty in the matter. 'Every man over against his house' is the principle I desire to commend to you as going a long way to solve the problem of how to sweeten the foul life of our modern cities. The story from which my text is taken does not need to detain us long. Nehemiah and his little band of exiles have come back to a ruined Jerusalem. Their first care is to provide for their safety, and the first step is to know the exact extent of their defencelessness. So we have the account of Nehemiah's midnight ride amongst the ruins of the broken walls. And then we read of the co-operation of all classes in the work of reconstruction. 'Many hands made light work.' Men and women, priests and nobles, goldsmiths, apothecaries, merchants, all seized trowel or spade, and wheeled and piled. One man puts up a long length of wall, another can only manage a little bit; another undertakes the locks, bolts, and bars for the gates. Roughly and hastily the work is done. The result, of course, is very unlike the stately structures of Solomon's or of Herod's time, but it is enough for shelter. We can imagine the sigh of relief with which the workers looked upon the completed circle of their rude fortifications.
