“Dear brothers and sisters, be sure that you do not lose your joy. Do not be satisfied to be a miserable believer. Depend upon it, greater importance attaches to holy happiness than most people think. As you are happy in the Lord you will be able to praise his name. Rejoice in the Lord, that you may praise him.”

Charles Spurgeon, “A Life-long Occupation,” on Hebrews 13:15 , Metropolitan Tabernacle Pulpit [Ages Software], p. 733.
