Joab here appears at his best. A great occasion, involving great peril for the army and the kingdom, calls forth, not only his eminent military qualities, but sentiments of piety and religious patriotism worthy of David himself. He presents an example worthy of imitation by commanders of armies; but we take his words as adapted to guide and animate the soldiers of Christ in their warfare against error and sin. They Call attention to three duties incumbent upon individual Christians, the several bands of each division of the Christian army, and the several divisions themselves.

I. MUTUAL HELP. (Ver. 11.) The servants of Christ are engaged in the endeavour to conquer the world for him, and, in pursuing it, have to fight against enemies of various kinds. In this warfare they ought to cheerfully cooperate, and, as opportunity may arise, help each other. Much mutual assistance they cannot but render, however any might desire to confine the benefits of their activity to their own party. Every hymn book testifies to this. No individual or section can do good work without helping others. But there should be more of conscious and hearty cooperation.

1. Why it should be so.

(1) The cause is one - the cause of Christ our King, the defence and extension of his kingdom, the cause of truth and righteousness and human salvation.

(2) Christians are comrades in the same army. They should cherish the feeling of brotherhood, realize that they are fighting against common foes, and be glad to encourage and help each other. The success of any is the success of all, and should be so regarded; the failure of any should be a trouble to all; and, if any can aid their brethren to turn threatening defeat into victory, their aid should be cheerfully afforded and joyfully accepted.

(3) The need is urgent. The spiritual necessities of men, the special needs in particular cases. The field is extensive; the opposing forces numerous, powerful, and incessantly vigilant and active. The utmost exertions of all are required. To hold back, to refuse cooperation with fellow soldiers because they belong not to our regiment or division of the army, to observe with pleasure the failure of any of them, or to waste energies and resources in fierce conflicts with one another, is to be disloyal to their Sovereign,, unbrotherly to each other, and unfaithful to the souls of men.

2. Why it often is not so.

(1) Deficiency of spiritual insight. Incapacity, voluntary or involuntary, to discern:

(a) The real nature of the kingdom of Christ. That it is essentially spiritual, consisting in "righteousness and peace and joy in the Holy Ghost;" that "he that in these things serveth Christ is acceptable to God, and approved of men" (Romans 14:17, 18); and that in Christ Jesus nothing avails but "a new creature," "faith which worketh by love," and "the keeping of the commandments of God" (Galatians 6:15; Galatians 5:6; 1 Corinthians 7:19).

(b) The essential qualities of Christ's soldiers, which are not the dress they wear, nor the particular drill to which they are accustomed, but love and loyalty to Christ.

(2) Deficiency of spiritual affections. Want of supreme and ardent love for Christ and his kingdom, and for his servants as such. These deficiencies of mind and heart act and react on each other, and they open the way for all kinds of blundering and perversity. Fellow soldiers are mistaken for enemies, and treated as such. The great cause is made practically subordinate to matters infinitely small in comparison. Sectarian rivalry takes the place of Christian cooperation; or a worse thing happens - petty personal ambition and selfishness, or likings and dislikings, dominate, separating those who should be acting together, and introducing low, worldly principles into a region where the spiritual should alone reign. Pride, jealousy, envy, uncharitableness, perhaps the merest avarice, reduce to a fraction, if they do not altogether extinguish, those noble Christian feelings which Christianity inspires, and which would impel brothers to own brothers, cordially to render or receive help in the common work, to rejoice in each other's successes, and sorrow for each other's reverses.

3. Who should take the lead in effecting cooperation? Joab addresses Abishai, his fellow commander; and it is just the leaders and commanders in Christ's army who should be foremost in promoting a good understanding between its various bands, and inducing them to work together. But, alas! they are often foremost in promoting alienation and separation. The people are frequently more disposed to be friendly towards each other than the clergy.

II. COURAGE. (Ver. 12.) In war this is essential to success. In the Christian warfare it is not so obviously or universally required. It is, however, still required in many cases. When unpopular truth has to be proclaimed, when strongholds of sin or superstition have to be assailed, when the evangelization of barbarous tribes is attempted, or perilous climates have to be encountered, the Christian soldier must be prepared to endure hardship, suffering, or death. Even the ridicule which not unfrequently assails the earnest Christian calls for a good deal of courage. Joab sought to inspire his brother, and through him the soldiers under his command, with courage, by reminding him that it was "for our people, and for the cities of our God," that they were about to fight. In like manner Christians may be exhorted to "be of good courage" and "play the men" for the Church of God, and for the sake of the world which they aim to conquer for Christ. Joab might have added, "for our king;" and the strongest and most animating consideration for us is that we are witnessing and working and fighting for our great King, the Lord Jesus Christ. He is worth living for, suffering for, dying for. He has gone before us in the labour and the suffering. He is present with us. His eye is upon each of us. He will overlook no true-hearted soldier of his when he distributes the rewards of victory. "If we suffer, we shall also reign with him" (2 Timothy 2:12).

III. RESIGNATION. Those who engage in war, though they may hope for victory, must be prepared for defeat. "The battle" is not always "to the strong" (Ecclesiastes 9:11) or the brave. Nor in the better warfare can we "command success" in this or that particular encounter, however faithful or brave or zealous we may be. We are to recognize, like Joab, that "the Lord" is over all, and be content that he should "do that which seemeth him good." Not that we are required to be resigned to ultimate failure, for we are assured of final and complete victory.

"The saints in all this glorious war
Shall conquer, though they're slain."

Nor are the courage and devotedness of any single soldier lost. All the faithful contribute to the final triumph, and all shall unite in the song of victory, "The kingdoms of this world are become the kingdoms of our Lord, and of his Christ." "Alleluia: for the Lord God omnipotent reigneth!" "And he shall reign forever and ever" Revelation 11:15; Revelation 19:6). - G.W.

I. MUTUAL HELPFULNESS. As occasion demands, says Joab, you will help me, or I will help you. Now, this is a word for us all. God has so ordained that we are mutually dependent on one another; and I hardly know which of the two is worse, the self-conceit of the man who imagines he can stand alone, or the selfishness of the. man who has no instinctive desire to help his neighbour when in trouble. Why, away from religion altogether, it is our duty both to lean and to carry; for it, is seldom indeed that there is not a stronger than ourselves, who can render us aid; and equally seldom that there is not s feebler than ourselves, to whom we may do a service. Too often the sentiment of the world is, "every man for himself" — the survival, If not of the fittest, at least of the strongest. Let the bold and lithe push to the front, and the weak go to the wall. There is a great deal of this in business, as some of you well know; certain men, elbowing and driving forward, not caring whom they push over or trample under their feet, if only they are successful themselves. The result is that many a good, able worthy fellow, simply because he has not the audacity, the impudence, of others, is left behind and gets disheartened. Now it is here that Christian principle should come in, balancing and regulating the various elements at work, giving confidence to the weak and-generosity to the strong, and so securing the largest amount of success and happiness.

II. MANLY HEROISM, "Be of good courage, and let us behave ourselves valiantly." Never on field of battle did officer shout across to brother officer s nobler sentiment. The army has indeed, produced lame grand men, heroes in the truest sense of the world. But I would not for a moment wish to convey the impression that heroes are confined to campaigns and battlefields. I venture to assert that in the commonest spheres of civil and prosaic life may be found instances of an equally noble; though less showy, heroism. There are heroes of the workshop, of the counter, of the office, of the market-place, on whose courage may be put as severe a strain as though they stood upon the field of battle, amid the glitter of cold steel and the rattle of musketry. When a man has to fight with poverty, with losses, with bad debts, with disappointments, with temptations: and still keeps his head to the wind, battles on bravely, refuses to knock under, vows still to "trust in God and do the right," I say, though he has no epaulettes on his shoulders, nor medals on his breast, he is as truly s man and a hero as though he had stormed a citadel. "Be of good courage, and let us behave ourselves," would be an excellent motto for the employees in many a London establishment. You want the "courage" of your principles, and then no fear of your "behaviour." When a man's life is dominated by the one aim, not to make money, not to find idle pleasure, but to please his Master in heaven, it is wonderful how much respect he commands, and how much pure inward happiness he enjoys.

III. TRUE PATRIOTISM. Listen again to General Joab: "Be of good courage, brother, and let us behave ourselves valiantly for our people, and for the cities of our God." Now you will notice the motive which he adduced. Bravo! ye sons of Zeruiah! "God and our country" was their cry. It was no empty, silly Jingo shout, like that which we have heard in our own day from a hysteric rabble that clamour for glory, but would turn tail with the first shot that whizzed about their ears; it was a call to action and to danger, impelled by love to Israel, and to Israel's God. Sirs, patriotism is one of the noblest sentiments that can occupy the human breast; but .there is no patriotism so pure and disinterested as that which is kindled at the altar of love to God. Never was there a more remarkable instance of it than the dauntless British officer to whom I have already adverted. Self-negation characterised his whole career. After all his great work in China, General Gordon left the country as poor as he entered it, having refused all rewards. When a sum of £10,000 was forwarded to him by the Emperor, he divided it all amongst his troops. On his arrival in England he declined every honour, preferring to bury himself in obscurity. The very medals that were showered upon him he put no value upon, and would even have them melted down to provide relief for those who were in want. GENUINE PITY. "And let the Lord do that which is good in His sight." I do not venture to say that Joab was a saint, nor would I like to answer for many things which he did: but on this occasion, certainly, his conduct and language were admirable, and worthy of imitation. "Abishai," he seems to say, "you and I shall do our best, and leave the issue with God. We cannot command success, but we can do our duty, and leave the result in higher hands than our own." It is a fine thing to see a God-fearing soldier. It is an interesting feature of our time that there is in the British army a very considerable amount of deep and unaffected piety. Some of our highest officers, some of our most distinguished generals, both abroad and at home, are real men of God. They are none the less, but all, the more, valuable as soldiers. They have more pluck and less fear than the others A man is all the braver soldier for being a Christian. When true piety is engrafted on a fearless and gallant nature, it forms a splendid character. For a noble and beautiful Christianity, commend me to a converted soldier. "General Gordon," says one of the morning papers, "is not a man whose actions or whose fortunes can be estimated by the ordinary standard to which human affairs are submitted. His singularly pure and lofty character impresses every one with whom he is brought into contact. He believes himself to be always fulfilling a mission from a higher authority than any earthly government. A man of this heroic mould, who combines no small share of worldly wisdom with the integrity of a saint and the simplicity of a child, may walk securely in places where any other foot would slip. But, on the other hand, General Gordon would march quietly on to what he knew was certain destruction, if he believed that to do so was his duty."
