For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for? But if we hope for that we see not, then do we with patience wait for it. – Romans 8:24,25

Here is a test for us all. You may judge of a man by what he groans after. Some men groan after wealth, they worship Mammon. Some groan continually under the troubles of life; they are merely impatient-there is no virtue in that. Some men groan because of their great losses or sufferings; well, this may be nothing but a rebellious smarting under the rod, and if so, no blessing will come of it. But the man that yearns after more holiness, the man that sighs after God, the man that groans after perfection, the man that is discontented with his sinful self, the man that feels he cannot be easy till he is made like Christ, that is the man who is blessed indeed. May God help you, and help me, to groan all our days with that kind of groaning. I have said before, there is heaven in it, and though the word sounds like sorrow, there is a depth of joy concealed within,

“Lord, let me weep for nought but sin,
And after none but Thee;
And then I would, O that I might,
A constant weeper be.”

While you shall for a while sigh for more of heaven, you shall soon come to the abodes of blessedness where sighing and sorrow shall flee away. ~ C.H. Spurgeon
