1. Notice here, first, the solitary saint. Noah stands alone 'in his generations' like some single tree, green and erect, in a forest of blasted and fallen pines. 'Among the faithless, faithful only he.' His character is described, so to speak, from the outside inwards. He is 'righteous,' or discharging all the obligations of law and of his various relationships. He is 'perfect.' His whole nature is developed, and all in due symmetry and proportion; no beauty wanting, no grace cultivated at the expense of others. He is a full man; not a one-sided and therefore a distorted one. Of course we do not take these words to imply sinlessness. They express a relative, not an absolute, completeness. Hence we may learn both a lesson of stimulus and of hope. We are not to rest satisfied with partial goodness, but to seek to attain an all-round perfectness, even in regard to the graces least natural to our dispositions. And we can rejoice to believe that God is generous in His acceptance and praise. He does not grudge commendation, but takes account of the deepest desires and main tendencies of a life, and sees the germ as a full-blown flower, and the bud as a fruit. Learn, too, that solitary goodness is possible. Noah stood uninfected by the universal contagion; and, as is always the case, the evil around, which he did not share, drove him to a more rigid abstinence from it. A Christian who is alone 'in his generations,' like a lily among nettles, has to be, and usually is, a more earnest Christian than if he were among like-minded men. The saints in 'Caesar's household' needed to be very unmistakable saints, if they were not to be swept away by the torrent of godlessness. It is hard, but it is possible, for a boy at school, or a young man in an office, or a soldier in a barrack, to stand alone, and be Christlike; but only on condition that he yields to no temptation to drop his conduct to the level around him, and is never guilty of compromise. Once yield, and all is over. Flowers grow on a dunghill, and the very reeking rottenness may make the bloom finer. Learn, too, that the true place for the saint is 'in his generations.' If the mass is corrupt, so much the more need to rub the salt well in. Disgust and cowardice, and the love of congenial society, keep Christian people from mixing with the world, which they must do if they are to do Christ's work in it. There is a great deal too much union with the world, and a great deal too much separation from it, nowadays, and both are of the wrong sort. We cannot keep too far away from it, by abstinence from living by its maxims, and tampering with its pleasures. We cannot mix too much with it if we take our Christianity with us, and remember our vocation to be its light.
