“He Will Beautify the Meek with Salvation”
Psalm 149:4
4 For the Lord taketh pleasure in his people: he will beautify the meek with salvation.
Elder Bruce R. McConkie wrote:
“In the Sermon on the Mount, as given both to the Jews and to the Nephites, Christ promised that the meek shall inherit the earth. (Matt. 5:5; 3 Ne. 12:5.) David gave the same assurance to ancient Israel. (Ps. 37:11.) Few virtues have such inherent worth as meekness, for the meek are the godfearing and the righteous. They are the ones who willingly conform to the gospel standards, thus submitting their wills to the will of the Lord. They are not the fearful, the spiritless, the timid. Rather, the most forceful, dynamic personality who ever lived—He who drove the money changers from the temple, and with violence threw down their merchandising equipment (Matt. 21:12–13)—said of Himself, ‘I am meek and lowly in heart.’ (Matt. 11:29.)
“Meekness is a fruit of the Spirit. (Gal. 5:23.) The Lord has said that His grace is sufficient for the meek in this life (Ether 12:26), and that in eternity they shall have an inheritance in the celestial kingdom. (Ps. 149:4.) When the earth is sanctified, cleansed from all unrighteousness, and prepared for celestial glory, then the meek shall claim their promised inheritance. (D&C 88:16–32.)”
