After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb. -Revelation 7:9-10

The bliss of the saved in glory teaches us to long for it. It is legitimate to long for heaven-not to long to escape from doing our duty here. It is idleness to be always wanting to have done with this world-it is clear sloth-but to be longing to be where Jesus is, is only natural and gracious. Should not the child long to go home from the school? Should not the captive pine for liberty? Should not the traveller in foreign lands long to see his native country? Should not the bride, the married wife, when she has been long away from her husband, long to see his face? If you did not long for heaven, surely you might question whether heaven belonged to you. If you have ever tasted of the joys of the saints, as believers do on earth, you will sing with full soul:

“My thirsty spirit faints
To reach the land I love
The bright inheritance of saints,
Jerusalem above.”

You may long for this…be patient until you get there. As it will be such a blessed place when you arrive, don’t trouble about the difficulties of the way. You know our hymn:

“The way may be rough, but it cannot be long.”

“Let us fill it with hope, and cheer it with song.”

~ C.H. Spurgeon
