Charles H. Spurgeon on Psalms 149:2

Let Israel rejoice, etc. Give us, oh, give us the man who sings at his work! Be his occupation what it may, he is equal to any of those who follow the same pursuit in silent sullenness. He will do more in the same time —he will do it better —he will persevere longer. One is scarcely sensible of fatigue whilst he marches to music. The very stars are said to make harmony as they revolve in their spheres. Wondrous is the strength of cheerfulness, altogether past calculation its powers of endurance. Efforts to be permanently useful must be uniformly joyous —a spiritual sunshine —graceful from very gladness —beautiful because bright. —Thomas Carlyle.
