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

It is a vastly better thing to see “Jesus only,” as a matter of perpetuity, than to see Moses and Elias with Jesus. It is night, I know it, for I see the moon and stars. The morning cometh, I know it cometh, for I see no longer many stars, only one remains, and that the morning star. But the full day has arrived, I know it has, for I cannot even see the morning star; all those guardians and comforters of the night have disappeared; I see the sun only. Now, inasmuch as every man prefers the moon to midnight and to the twilight of dawn, the disappearance of Moses and Elias, indicating the full noontide of light, was the best thing that could happen. Why should we wish to see Moses? The ceremonials are all fulfilled in Jesus; the law is honored and fulfilled in Him. Let Moses go, his light is already in “Jesus only.” And why should I wish to retain Elias? The prophecies are all fulfilled in Jesus, and the preparation of which Elias preached Jesus brings with Himself. Let, then, Elias go, his light also is in “Jesus only.” It is better to see Moses and Elias in Christ, than to see Moses and Elias with Christ. The absence of some things betokens a higher state of things than their presence…So the Christian wants not the symbols of Moses, or the preparations of Elias, for Christ is all, and we are complete in Him. He who is conversant with the higher walks of sacred literature and reads in the golden book of Christ’s heart, may safely lay the legal school-book by. ~ C.H. Spurgeon
