By thy words thou shalt be justified, and by thy words thou shalt be condemned. Matthew 12:37. OHC 291.1
God has given every youth the talent of speech to be improved for Him. This is a most important trust.... Let your words be life-giving, pointing those around you to the Saviour. Let them bring sunshine instead of gloom, harmony instead of animosity. Say nothing that you would not be willing to say in the presence of Jesus and the angels. Utter no word that will stir up strife in another heart. However provoked you may feel, restrain the hasty word. If you are Christlike in speech and action, those who associate with you will be blessed by the association. Righteous words and deeds have a more powerful influence for good than all the sermons that can be preached.20The Youth's Instructor, January 1, 1903. OHC 291.2
Let us guard against speaking words that discourage. Let us resolve never to engage in evilspeaking and backbiting. Let us refuse to serve Satan by implanting seeds of doubt. Let us guard against cherishing unbelief, or expressing it to others. Many, many times I have wished that there might be circulated a pledge containing a solemn promise to speak only those words that are pleasing to God. There is a great need for such a pledge as there is for one against the use of intoxicating liquor. Let us begin to discipline the tongue, remembering always that we can do this only by disciplining the mind, for “out of the abundance of the heart the mouth speaketh.” Matthew 12:34. OHC 291.3
Through the help that Christ can give, we shall be able to learn to bridle the tongue. Sorely as He was tried on the point of hasty and angry speech, He never once sinned with His lips. With patient calmness He met the sneers, the taunts, and the ridicule of His fellow workers at the carpenter's bench. Instead of retorting angrily, He would begin to sing one of David's beautiful psalms; and His companions, before realizing what they were doing, would unite with Him in the hymn. What a transformation would be wrought in this world if men and women today would follow Christ's example in the use of words! 21The Review and Herald, May 26, 1904. OHC 291.4
