After thus reviewing some of the good uses of the tongue, and observing how they depend on the state of the heart,[361] we cannot help again laying stress on the need of a wise self-control in all that we say. He that refraineth his lips doeth wisely. A man of understanding holdeth his peace.[362] "He that spareth his words hath knowledge."[363] "Even a fool when he holdeth his peace is counted wise, when he shutteth his lips he is prudent."[364] If only the uninstructed and foolish person has sense enough to perceive that wisdom is too high for him he will not open his mouth in the gate,[365] and so in listening he may learn. "Of thine unspoken word thou art master," says an Indian proverb, "but thy spoken word is master of thee." We are to be swift to hear, but slow to speak: we are to ponder all that we hear, for it is only the simple that believes every word, the prudent man looks well to his going.[366] As St. James says, summing up all the teaching that we have reviewed, "If any man thinketh himself to be religious, while he bridleth not his tongue, but deceiveth his heart, this man's religion is vain."[367] And now there is only one other point to be noticed, but it is one of vast importance. As we realize the immense power of the tongue and the great issues which depend on its right or wrong employment; as we sum up all the evil which its tiny unobserved movements can accomplish, and all the rich blessings which it is, under right supervision, capable of producing; and as from personal experience we recognise how difficult it is to bridle the unruly member, how difficult it is to check the double fountain so that it shall send forth sweet waters only, and no bitter, we may be awed into an almost absolute silence, and be inclined to put away the talent of speech which our Lord has given to us, not daring to use it lest in using we should abuse it. But here is the answer to our misgiving: the plans and preparations of our hearts belong to us, but the answer of the tongue is from the Lord.[368] This most uncontrollable organ of the body can be put under our Lord's control. He is able to give us "a mouth and wisdom," and to make our words not our own but the utterance of His Holy Spirit. There may be "an ocean round our words which overflows and drowns them," the encircling influences of God, turning even our faultiest speech to good account, neutralising all our falterings and blunderings, and silencing our follies and perversities.
