The humble are happy when they see other people boasting in the Lord.
“My soul makes its boast in the Lord; let the humble hear and be glad” (Psalm 34:2).
The humble are happy when other people magnify the Lord with thanksgiving.
“I will praise the name of God with a song; I will magnify him with thanksgiving. . . . When the humble see it they will be glad” (Psalm 69:30, 32).
Why are the humble happy when others boast in the Lord and magnify the Lord with thanksgiving?
Because humility is most fundamentally a trembling love for the majesty of God and secondarily a trembling sense of our sin and smallness and dependence.
