As for me, I will behold Thy face in righteousness: I shall be satisfied, when I awake, with Thy likeness. – Psalm 15:17

Have you ever lived on the future, and said, “As for me I shall have somewhat, by-and-bye?” Why, this is the highest motive that can actuate a man. I suppose this was what made Luther so bold, when he stood before his great audience of kings and lords, and said, “I stand by the truth that I have written, and will so stand by it till I die; so help me God!” Me thinks he must have said, “I shall be satisfied by-and-bye. I am not satisfied now, but I shall be soon.” For this the missionary ventures the stormy sea; for this he treads the barbarous shore; for this he goes into inhospitable climes, and risks his life, because he knows there is a payment to come by-and-bye. I sometimes laughingly tell my friends when I receive a favor from them, that I cannot return it, but set it up to my Master in heaven, for they shall be satisfied when they awake in His likeness. There are many things that we may never hope to be rewarded for here, but that shall be remembered before the throne hereafter, not of debt, but of grace. Like a poor minister I heard of, who, walking to a rustic chapel to preach, was met by a clergyman who had a far richer berth. He asked the poor man what he expected to have for his preaching. “Well,” he said, “I expect to have a crown.” “Ah!” said the clergyman, “I have not been in the habit of preaching for less than a guinea, anyhow.” “Oh!” said the other, “I am obliged to be content with a crown, and what is more, I do not have my crown now, but I have to wait for that in the future.” The clergyman little thought that he meant the “crown of life that fadeth not away!” Christian! live on the future; seek nothing here but expect that thou shalt shine when thou shalt come in the likeness of Jesus, with Him to be admired, and to kneel before His face adoringly. ~ C.H. Spurgeon
