(Mind, Character, and Personality Volume 2 657.1)
Mind Must Be Firmly Controlled—The youth should begin early to cultivate correct habits of thought. We should discipline the mind to think in a healthful channel and not permit it to dwell upon things that are evil. The psalmist exclaims, “Let the words of my mouth, and the meditation of my heart, be acceptable in Thy sight, O Lord, my strength, and my Redeemer” (Psalm 19:14). (2MCP 657.1) MC VC
