11 And they put a question to him, saying, Why do the scribes say that Elijah has to come first? 12 And he said to them, Truly, Elijah does come first, and puts all things in order; and how is it said in the Writings that the Son of man will go through much sorrow and be made as nothing? 13 But I say to you that Elijah has come, and they have done to him whatever they were pleased to do, even as the Writings say about him.
Matthew Henry's Commentary on Mark 9:11-13
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.
