4. Solomon says, “He that ruleth his spirit (his mind), is better than he that taketh a city.” Prov. 16:32. If, then, thou desirest to be a valiant conqueror, and to gain an immortal victory, conquer thyself; subdue thy passions, mortify thy pride, quell thine ambition, and destroy every inordinate lust with which thou art assailed; and thus shalt thou overthrow the kingdom of Satan, who, by means of such sins, ruleth in the world. Many have signalized themselves by the capture of towns and cities; but, alas! how few are they who, in a higher sense, may be denominated _conquerors of the world_! 5. If thou yieldest too far to the flesh, thou destroyest thy soul. It is surely better that the soul overcome, and that the body also be preserved, than that, the body overcoming, both body and soul should be destroyed together. 6. This contest, though attended with various trials and difficulties, will, however, issue in a glorious victory and a heavenly crown: “Be thou faithful unto death,” saith the Captain of our salvation, “and I will give thee a crown of life.” Rev. 2:10. And the disciple that lay in his bosom tells us, “This is the victory that overcometh the world, even our faith.” 1 John 5:4. Thou wilt say, What is it to overcome the world? We answer, It is the world within us, which is here principally meant. Overcome thy _self_, and then the victory over the world is thine. 7. Some may, perhaps, be here ready to inquire, “What, if sin sometimes closely beset me, and bear me away against my will; must I be excluded from the number of God’s children, according to that saying of St. John, ‘He that committeth sin is of the devil’?” 1 John 3:8. To this it must be replied: If thou feelest the conflict of the Spirit against the flesh, and art grieved that thou sometimes doest things which thou wouldst not, it is an evidence that, amidst the infirmities which encompass thee, thy faith and thy spirit struggle against the flesh, and are opposed to it. St. Paul himself teaches us that this warfare has place even in godly and believing souls, when he says, “I see another law in my members warring against the law of my mind (that is, against the new, inward man), and bringing me into captivity to the law of sin which is in my members” (Rom. 7:23); thus causing him sometimes to do the things which he would not. To will, was present with him; but to perform the good which he would, he was not always able; inasmuch as he could not do of himself the good which he would, while to do the evil which he would not, was always easy to him. Hence he exclaims, “O wretched man that I am! who shall deliver me from the body of this death?” Rom. 7:24. And to this agrees what Christ himself says: “The spirit indeed is willing, but the flesh is weak.” Matt. 26:41; Mark 14:38.
