2 Six days later, three of them did see it. Jesus took Peter, James, and John and led them up a high mountain. His appearance changed from the inside out, right before their eyes. 3 His clothes shimmered, glistening white, whiter than any bleach could make them. 4 Elijah, along with Moses, came into view, in deep conversation with Jesus. 5 Peter interrupted, "Rabbi, this is a great moment! Let's build three memorials - one for you, one for Moses, one for Elijah." 6 He blurted this out without thinking, stunned as they all were by what they were seeing. 7 Just then a light-radiant cloud enveloped them, and from deep in the cloud, a voice: "This is my Son, marked by my love. Listen to him." 8 The next minute the disciples were looking around, rubbing their eyes, seeing nothing but Jesus, only Jesus. 9 Coming down the mountain, Jesus swore them to secrecy. "Don't tell a soul what you saw. After the Son of Man rises from the dead, you're free to talk." 10 They puzzled over that, wondering what on earth "rising from the dead" meant. 11 Meanwhile they were asking, "Why do the religion scholars say that Elijah has to come first?" 12 Jesus replied, "Elijah does come first and get everything ready for the coming of the Son of Man. They treated this Elijah like dirt, much like they will treat the Son of Man, who will, according to Scripture, suffer terribly and be kicked around contemptibly." 13
14 When they came back down the mountain to the other disciples, they saw a huge crowd around them, and the religion scholars cross-examining them.

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.
Commentary on Mark 9:14-29
(Read Mark 9:14-29)
The father of the suffering youth reflected on the want of power in the disciples; but Christ will have him reckon the disappointment to the want of faith. Very much is promised to our believing. If thou canst believe, it is possible that thy hard heart may be softened, thy spiritual diseases may be cured; and, weak as thou art, thou mayest be able to hold out to the end. Those that complain of unbelief, must look up to Christ for grace to help them against it, and his grace will be sufficient for them. Whom Christ cures, he cures effectually. But Satan is unwilling to be driven from those that have been long his slaves, and, when he cannot deceive or destroy the sinner, he will cause him all the terror that he can. The disciples must not think to do their work always with the same ease; some services call for more than ordinary pains.
