But let the righteous be glad; let them rejoice before God: yea, let them exceedingly rejoice. – Psalm 68:3

God always intended that His chosen, called, and converted people should be a rejoicing people. He created you on purpose that you should yourselves be happy, and bring happiness to others. Do you not know that His name is the happy God, and nothing gives Him greater happiness than to give happiness to His creatures? Do you think you were chosen to be a groaner all your days? Were you called to misery, dear brother? Does Jesus Christ say, “Come unto Me, all ye that labor and are heavy laden, and I will make you doleful”? Does He say, “Take My yoke upon you, and learn of Me, and ye shall find agony in your hearts”? No; but He talks about rest, and peace, and joy, and blessedness.

Different people have different ways, you know; and some love to be comfortably wretched. But I find myself miserable only when I keep away from my Lord and His work of new-creation. I have always found hitherto that when I can get under the shadow of His wings, my soul is at rest, and I look upon that restfulness and happiness as the work and fruit of the Spirit-“the fruit of the Spirit is joy and peace.”

He has created His people a rejoicing: yea, His people to be a joy. Ours is a heritage of joy and peace. My dear brethren and sisters, if anybody in the world ought to be happy, we are the people. How large our obligations! How boundless our privileges! How brilliant our hopes! ~ C.H. Spurgeon
