9:28-36 Christ's transfiguration was a specimen of that glory in which he will come to judge the world; and was an encouragement to his disciples to suffer for him. Prayer is a transfiguring, transforming duty, which makes the face to shine. Our Lord Jesus, even in his transfiguration, was willing to speak concerning his death and sufferings. In our greatest glories on earth, let us remember that in this world we have no continuing city. What need we have to pray to God for quickening grace, to make us lively! Yet that the disciples might be witnesses of this sign from heaven, after awhile they became awake, so that they were able to give a full account of what passed. But those know not what they say, that talk of making tabernacles on earth for glorified saints in heaven.

29. as he prayed, the fashion, &c.—Before He cried He was answered, and while He was yet speaking He was heard. Blessed interruption to prayer this! Thanks to God, transfiguring manifestations are not quite strangers here. Ofttimes in the deepest depths, out of groanings which cannot be uttered, God's dear children are suddenly transported to a kind of heaven upon earth, and their soul is made as the chariots of Amminadab. Their prayers fetch down such light, strength, holy gladness, as make their face to shine, putting a kind of celestial radiance upon it (2Co 3:18, with Ex 34:29-35).

raiment white, &c.—Matthew says, "His face did shine as the sun" (Mt 17:2), and Mark says (Mr 9:3), "His raiment became shining, exceeding white as snow, so as no fuller on earth can white them" (Mr 9:3). The light, then, it would seem, shone not upon Him from without, but out of Him from within; He was all irradiated, was in one blaze of celestial glory. What a contrast to that "visage more marred than men, and His form than the sons of men!" (Isa 52:14).
