Live 'worthy of the gospel,' then. How grand the unity and simplicity thus breathed into our duties and through our lives! All duties are capable of reduction to this one, and though we shall still need detailed instruction and specific precepts, we shall be set free from the pedantry of a small scrupulous casuistry, which fetters men's limbs with microscopic bands, and shall joyfully learn how much mightier and happier is the life which is shaped by one fruitful principle, than that which is hampered by a thousand regulations. Nor is such an all-comprehensive precept a mere toothless generality. Let a man try honestly to shape his life by it; and he will find soon enough how close it grips him, and how wide it stretches, and how deep it goes. The greatest principles of the gospel are to be fitted to the smallest duties. Indeed that combination--great principles and small duties--is the secret of all noble and calm life, and nowhere should it be so beautifully exemplified as in the life of a Christian man. The tiny round of the dew-drop is shaped by the same laws that mould the giant sphere of the largest planet. You cannot make a map of the poorest grass-field without celestial observations. The star is not too high nor too brilliant to move before us and guide simple men's feet along their pilgrimage. 'Worthy of the gospel' is a most practical and stringent law. And it is an exclusive commandment too, shutting out obedience to other codes, however common and fashionable they may be. We are governed from home, and we give no submission to provincial authorities. Never mind what people say about you, nor what may be the maxims and ways of men around you. These are no guides for you. Public opinion (which only means for most of us the hasty judgments of the half-dozen people who happen to be nearest us), use and wont, the customs of our set, the notions of the world about duty, with all these we have nothing to do. The censures or the praise of men need not move us. We report to headquarters, and subordinates' estimate need be nothing to us. Let us then say, 'With me it is a very small matter that I should be judged of men's judgment. He that judgeth me is the Lord.' When we may be misunderstood or harshly dealt with, let us lift our eyes to the lofty seat where the Emperor sits, and remove ourselves from men's sentences by our 'appeal unto Caesar'; and, in all varieties of circumstances and duty, let us take the Gospel which is the record of Christ's life, death, and character, for our only law, and labour that, whatever others may think of us, we 'may be well pleasing to Him.'
