91 And he said to them, "Truly, I say to you, there are some standing here who will not taste death before they see that the kingdom of God has come with power."
2 And after six days Jesus took with him Peter and James and John, and led them up a high mountain apart by themselves; and he was transfigured before them, 3 and his garments became glistening, intensely white, as no fuller on earth could bleach them. 4 And there appeared to them Eli'jah with Moses; and they were talking to Jesus. 5 And Peter said to Jesus, "Master, it is well that we are here; let us make three booths, one for you and one for Moses and one for Eli'jah." 6 For he did not know what to say, for they were exceedingly afraid. 7 And a cloud overshadowed them, and a voice came out of the cloud, "This is my beloved Son; listen to him." 8 And suddenly looking around they no longer saw any one with them but Jesus only. 9 And as they were coming down the mountain, he charged them to tell no one what they had seen, until the Son of man should have risen from the dead. 10 So they kept the matter to themselves, questioning what the rising from the dead meant.

Commentary on Mark 9:1-13
(Read Mark 9:1-13)
Here is a prediction of the near approach Christ's kingdom. A glimpse of that kingdom was given in the transfiguration of Christ. It is good to be away from the world, and alone with Christ: and how good to be with Christ glorified in heaven with all the saints! But when it is well with us, we are apt not to care for others, and in the fulness of our enjoyments, we forget the many wants of our brethren. God owns Jesus, and accepts him as his beloved Son, and is ready to accept us in him. Therefore we must own and accept him as our beloved Saviour, and must give up ourselves to be ruled by him. Christ does not leave the soul, when joys and comforts leave it. Jesus explained to the disciples the prophecy about Elias. This was very suitable to the ill usage of John Baptist.
