This, like the other general rules of the gospel, is familiar enough to us all in its own words; but we are very apt to forbear making the application of it. In fact, he who were to apply it perfectly would be a perfect Christian: for a life of which every word and deed were said and done in the name of the Lord Jesus, would be a life indeed worthy of the children of God, and such as they lead in heaven; it would leave no room for sin to enter. The art of our enemy has been therefore to make us leave this command of the apostle's in its general sense, and avoid exploring, so to speak, all the wisdom contained within it. Certain actions of our lives, our religious services, the more solemn transactions in which we are engaged, we are willing to do in Christ's name; but that multitude of common words and ordinary actions by which more than sixty-nine out of our seventy years are filled, we take away from our Lord's dominion, under the foolish, and hypocritical pretence that they are too trifling and too familiar to be mixed up with the thought of things so solemn. This is one fault, and by far the most common. We make Christ's service the business only of a very small portion of our lives; we hallow only a very small part of our words and actions by doing them in his name. Unlike our Lord's own parable, where he compares Christianity to leaven hidden in the three measures of meal till the whole was leavened, the practice rather has been to keep the leaven confined to one little corner of the mass of meal; to take care that it should not spread so as to leaven the whole mass; to keep our hearts still in the state of the world when Christ visited it--"the light shineth in darkness, and the darkness comprehended it not;" that is, it did not take the light into itself so as to be wholly enlightened: the light shone, and there was a bright space immediately around it; but beyond there was a blackness of darkness into which it vainly strove to penetrate.
