Therefore are they before the throne of God…For the Lamb which is in the midst of the throne shall feed them… -Revelation 7:15,17

Idle Christians are often unhappy Christians. I have met with many a spiritual dyspeptic always full of doubts and fears. Is there a young man here full of doubts and fears who has lost the light he once possessed, and the joy he once had? Dear brother, get to work. In cold weather the best way to be warm is not to get before a fire, but to work. Exercise gives a healthy glow, even amidst the frost. “I am doing something,” says one. Yes, with one hand; use the other hand. “Perhaps I should have too many irons in the fire,” says one. You cannot have too many. Put them all in, and blow the fire with all the bellows you can get. I do not believe any Christian man works too hard, and, as a rule, if those who kill themselves in Christ’s service were buried in a cemetery by themselves, it would be a long while before it would get filled. Work hard for Christ. It makes happy those who are in heaven to serve God day and night, and it will make you happy on earth. Do all you can. Another way is to have fellowship with Christ here. Read again this chapter. “He that sitteth on the throne shall dwell among them-He shall feed them.” Oh! if you want to be happy, live near to Jesus. Poor men are not poor when Christ lives in their house. Truly, sick men have their beds made easy when Christ is there. Has He not said, ” I will make his bed in all his sickness”? Only get fellowship with Jesus, and outward circumstances won’t distress you. The sun will not light on you, nor any heat. You will be like the shepherd on Salisbury Plain, who said it was good weather, though it rained hard. “It is weather,” said he, “that pleases me.” “How so?” said a traveller to him. “Well, sir,” he said, “it pleases God, and what pleases God pleases me.” “Good day!” said one to a Christian man. “I never had a bad day since I was converted,” said he. “They are all good now since Christ is my Saviour.” ~ C.H. Spurgeon
