“Keep thy tongue from evil, and thy lips from speaking guile.”Psalm 34:13.
(HP 174.1)
Speech is one of the great gifts of God. It is the means by which the thoughts of the heart are communicated. It is with the tongue that we offer prayer and praise to God. With the tongue we convince and persuade. With the tongue we comfort and bless, soothing the bruised, wounded soul. With the tongue we may make known the wonders of the grace of God. With the tongue also we may utter perverse things, speaking words that sting like an adder.

Only through Christ can we gain the victory over the desire to speak hasty, un-Christlike words.

The Holy Spirit can make the tongue a savor of life unto life.—The Review and Herald, May 12, 1910.

God wants us to be a help and strength to one another. He wants us to speak words of hope and courage.—The General Conference Bulletin, April 23, 1901.
