There is no other way to heaven except by way of courageous warfare. This is the way ordained by God: “And I will put enmity” (Gen. 3:15). You have chosen this way when you entered into the kingdom of Christ and placed yourself under His banner. Or on the other hand: you must either sever yourself from the covenant, as a villain walk from this ensign, and relinquish God, heaven, and everything else; or you must courageously engage in battle in order thus to conquer the devil and his cohorts, the world and all that is in it, as well as sin and all its lusts.
The crown of glory must be worth so much to you; so precious must spiritual life and fellowship with God be to you, and such pleasure must you find in the will of God, that you will be willing to battle valiantly all the days of your life. Do not let this weigh heavily upon your heart, thinking, “Must I be in arms and engage in warfare my entire lifetime? That is indeed a distasteful way and there is no way whereby I will persevere.” Yes, heaven must be that precious to you; or else you must not relinquish it.
Be it known, however, that to battle courageously is not such a heavy task as you allow yourself to believe. To always battle and succumb, or always to be equally matched in force, causing the outcome of the battle to be in doubt, is indeed a heavy task. It is a joyous task, however, to conquer as you are fighting, to proceed while conquering one city after another, and to humiliate the enemy battle after battle. Such will be the case if you but conduct yourself courageously, commensurate with you strength—be it that you battle as a child, a young man, or a man. You are so fearful of the battle because you do not proceed courageously, instead, due to your laxity, carelessness and lack of seriousness you give the enemy the opportunity to get the advantage over you. This makes them more courageous and you become weaker. Therefore, lift yourself up in the ways of the Lord and courageously engage yourself. Resist the devil and he will flee from you.
If your sword is too short, take one step forward.
There's no such thing as a crowded battlefield. Battlefields are lonely places.
The soldier, above all men, is required to practice the greatest act of religious training [sacrifice]. In battle, in the face of danger and death, he discloses those divine attributes which his Maker gave when He created man in His own image. No physical courage and no brute instinct can take the place of divine help that alone can sustain him. However horrible the instances of war may be, the soldier who is called upon to offer and to give his life for his country, is the noblest development of mankind.
Today you cannot effectively fight for freedom and not be attacked, and those who think they can are deceiving themselves. While I do not believe in stepping out of the path of duty to pick up a cross I do not need, a man is a coward who refuses to pick up a cross that clearly lies within his path.
A man must not only stand for the right principles, but he must also fight for them. Those who fight for principle can be proud of the friends they've gained and the enemies they've earned.
