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 Cæsar'; 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.'
III. Further, our text bids the colonists fight for the advance of the dominions of the City.
Like the armed colonists whom Russia and other empires had on their frontier, who received their bits of land on condition of holding the border against the enemy, and pushing it forward a league or two when possible, Christian men are set down in their places to be 'wardens of the marches,' citizen soldiers who hold their homesteads on a military tenure, and are to 'strive together for the faith of the gospel.'
There is no space here and now to go into details of the exposition of this part of our text. Enough to say in brief that we are here exhorted to 'stand fast'; that is, as it were, the defensive side of our warfare, maintaining our ground and repelling all assaults; that this successful resistance is to be 'in one spirit,' inasmuch as all resistance depends on our poor feeble spirits being ingrafted and rooted in God's Spirit, in vital union with whom we may be knit together into a unity which shall oppose a granite breakwater to the onrushing tide of opposition; that in addition to the unmoved resistance which will not yield an inch of the sacred soil to the enemy, we are to carry the war onwards, and, not content with holding our own, are with one mind to strive together for the faith of the gospel. There is to be discipline, then, and compact organisation, like that of the legions whom Paul, from his prison among the Prætorian guards, had often seen shining in steel, moving like a machine, grim, irresistible. The cause for which we are to fight is the faith of the gospel, an expression which almost seems to justify the opinion that 'the faith' here means, as it does in later usage, the sum and substance of that which is believed. But even here the word may have its usual meaning of the subjective act of trust in the gospel, and the thought may be that we are unitedly to fight for its growing power in our own hearts and in the hearts of others. In any case, the idea is plainly here that Christian men are set down in the world, like the frontier guard, to push the conquests of the empire, and to win more ground for their King.
