The one who is wise in heart is called discerning, and kind speech increases persuasiveness.
[Prov 16:21 NET]
Life is very largely made up of words. They are not so emphatic, perhaps, as deeds. Deeds are more deliberate expressions of thought. One of the most remarkable authors of the New Testament has said, If any man offend not in word, the same is a perfect man. It is very often a test of victory in Christian life. Our triumph in this often depends on what we say, or what we do not say. It is said by James of the tongue, It is set on fire of hell. The true Christian, therefore, is righteous in his ways and upright in his words. His deeds appeal to men; but in speech he is looking up, for God is listening. His words are sent upward and recorded for the judgment. I believe that this is an actual fact, and I can almost fancy that the skies above, which seem so transparent, the beautiful blue ether over our heads, is like a waxen tablet with a finely sensitive surface, and receives an impression of every word we speak, and that then these tablets are hardened and preserved for the eternal judgment. So we should speak, dear friends, with our eyes ever upward, never forgetting that we shall some day meet the words that we have spoken.
