Oh! you say, is that all that is required of us to insure our salvation--to keep clear of mortal sin? That is nothing new; we knew that all along; to go that far is not much; we can do that easily enough. Can you, indeed? Perhaps it is easy enough to avoid mortal sin for a time, when there is fervor, or particular grace, or little temptation; but is it easy to do so for one's whole life? Is it easy to do so when one's fervor is worn off, and distractions of all kinds occupy the mind, and when in this state strong temptations beset one? Who ever says this, shows that he has little knowledge of himself, and little experience in affairs of the soul. You may avoid sin a little while, but you will fall, as sure as you live, if your mind is not set against sin, actively and habitually, so as to turn away from it with horror in the moment of temptation. No; in order not to fall, our whole life must be directed toward God. The eternal truths, heaven, hell, death, judgment, must pass frequently through our minds and take up our thoughts. In the words of Scripture, we must keep our lamps trimmed, and well supplied with oil, lest they go out. {101} Our souls must be trimmed with holy meditations, and the oil of good works supplied in abundance must keep the flame of love to God burning brightly in our hearts, or else it will go out. It will fade away gradually for want of nourishment, until it is gone. We cannot keep clear even of mortal sin, unless we are thoroughly in earnest about it, and make a business of it. When our Lord says, "Love the Lord thy God with thy whole heart and thy whole soul, and thy whole mind," He means to say: Put your heart and soul in the business of your salvation. Make a sure thing of it by the energy and determination you apply to it.
