Charles H. Spurgeon on Psalms 100:1

Make a joyful noise unto the LORD, all ye lands. This is a repetition of Ps 98:4. The original word signifies a glad shout, such as loyal subjects give when their king appears among them. Our happy God should be worshipped by a happy people; a cheerful spirit is in keeping with his nature, his acts, and the gratitude which we should cherish for his mercies. In every land Jehovah's goodness is seen, therefore in every land should be be praised. Nearer will the world be in its proper condition till with one unanimous shout it adores the only God. O ye nations, how long will ye blindly reject him? Your golden age will never arrive till ye with all your hearts revere him.
