On the whole, this catalogue brings out the importance to be attached to sins of speech, which are ranked here as in parallel lines with the grossest forms of animal passion. Men's words ought to be fountains of consolation and sources of illumination, encouragement, revelations of love and pity. And what are they? What floods of idle words, foul words, words that wound like knives and sting and bite like serpents, deluge the world! If all the talk that has its sources in these evils rebuked here, were to be suddenly made inaudible, what a dead silence would fall on many brilliant circles, and how many of us would stand making mouths but saying nothing.
All the practical exhortations of this section concern common homely duties which everybody knows to be such. It may be asked--does Christianity then only lay down such plain precepts? What need was there of all that prelude of mysterious doctrines, if we are only to be landed at last in such elementary and obvious moralities? No doubt they are elementary and obvious, but the main matter is--how to get them kept. And in respect to that, Christianity does two things which nothing else does. It breaks the entail of evil habits by the great gift of pardon for the past, and by the greater gift of a new spirit and life principle within, which is foreign to all evil, being the effluence of the spirit of life in Christ Jesus.
Therefore the gospel of Jesus Christ makes it possible that men should slay themselves, and put on the new life, which will expel the old as the new shoots on some trees push the last year's lingering leaves, brown and sere, from their places. All moral teachers from the beginning have agreed, on the whole, in their reading of the commandments which are printed on conscience in the largest capitals. Everybody who is not blind can read them. But reading is easy, keeping is hard. How to fulfil has been wanting. It is given us in the gospel, which is not merely a republication of old precepts, but the communication of new power. If we yield ourselves to Christ He will nerve our arms to wield the knife that will slay our dearest tastes, though beloved as Isaac by Abraham. If a man knows and feels that Christ has died for him, and that he lives in and by Christ, then, and not else, will he be able to crucify self. If he knows and feels that by His pardoning mercy and atoning death, Christ has taken off his foul raiment and clothed him in clean garments, then, and not else, will he be able, by daily effort after repression of self and appropriation of Christ, to put off the old man and to put on the new, which is daily being renewed into closer resemblance to the image of Him who created him.
