And, behold, there appeared unto them Moses and Elias talking with Him…And when they had lifted up their eyes, they saw no man, save Jesus only. – Matthew 17:3,8

Even the most precious things we treasure here below will disappear when fully realized in heaven. Beautiful for situation was the temple on Mount Zion, and though we believe not in the sanctity of buildings under the gospel, we love the place of solemn meeting where we are accustomed to offer prayer and praise; but when we enter into perfection we shall find no temple in heaven. We delight in our Sabbaths, and we would not give them up, but when we reach the Jerusalem above, we shall not observe the first day of the week above the rest, for we shall enjoy one everlasting Sabbath.

Do you remember when you were first of all convinced and awakened, what a great deal you thought of the preacher, and how much of the very style in which he spoke the gospel! But now, though you delight to listen to his voice, and find that God blesses you through him, yet you have sunk the thought of the preacher in the glory of the Master, you see no man save “Jesus only.” And as you grow in grace you will find that many doctrines and points of church government which once appeared to you to be all important, though you will still value them, will seem but of small consequence compared with Christ Himself. Like the traveller ascending the Alps to reach the summit of Mont Blanc; at first he observes that lord of the hills as one born among many, and often in the twistings of his upward path he sees other peaks which appear more elevated than that monarch of mountains; but when at last he is near the summit, he sees all the rest of the hills beneath his feet, and like a mighty wedge of alabaster Mount Blanc pierces the very clouds. So, as we grow in grace, other things sink and Jesus rises. They must decrease, but Christ must increase; until He alone fills the full horizon of your soul, and rises clear and bright and glorious up into the very heaven of God. O that we may thus see “Jesus only!” ~ C.H. Spurgeon
