Mark 16:12

Therefore the Lord performed outwardly in the eyes of the body what was happening within them in the eyes of the heart. For they themselves within were both loving and doubting, while the Lord outwardly was both present to them and yet did not reveal who He was. To those speaking about Him He showed His presence, but from those doubting Him He hid the appearance of His recognition.

After this, however, he was shown in another form to two of them, as they walked and went into the country. And they went and told it to the rest, but they did not believe them. How this happened, Luke explains more fully. But what …

But in a mystic sense we may understand that faith here labours, leading the active life, but there it reigns secure in the contemplative vision. Here we see His face through a glass, there we shall see the truth face to face, wherefore He was shown to them as they were walking, that is, labouring, in another form. And when it was told, the disciples did not believe, because they saw, like Moses, that which was not enough for them, for he said, show me thyself; (Exod. 33:18. Sept.) forgetting his flesh, he prays in this life for that which we hope for in the life to come.

"After this He appeared in another form to two of them on the road, as they were going into the village." About these two, Luke also speaks (Luke 24:13–35).

After that,....

His appearance to the eleven with the commission he gave them to set up his kingdom in the world, and full instructions and credentials in order thereunto,,

These two witnesses gave in their testimony to this proof of Christ's resurrection;

He appeared - unto two of them - These were the two who were going to Emmaus. The whole account is given by Luke, 24:13-34, where see the notes. Dr. Lightfoot’s criticism upon this passage is worthy of notice. “That, in the verses immediately going before, the discourse is of the two disciples going to Emmaus, is without all controversy.

Let us mark, in these verses, what abundant proof we have that our Lord Jesus Christ really rose again from the dead . In this one passage Mark records no less than three distinct occasions on which He was seen after His resurrection. First, he tells us, our Lord appeared to one witness, Mary Magdalene — then to two witnesses, two disciples walking into the country — and lastly to eleven witnesses, the eleven apostles all assembled together.

After that he appeared in another form--(compare Lu 24:16). unto two of them as they walked, and went into the country--The reference here, of course, is to His manifestation to the two disciples going to Emmaus, so exquisitely told by the Third Evangelist (see on Lu 24:13, &c.).

Let us mark, in these verses, what abundant proof we have that our Lord Jesus Christ really rose again from the dead . In this one passage Mark records no less than three distinct occasions on which He was seen after His resurrection. First, he tells us, our Lord appeared to one witness, Mary Magdalene — then to two witnesses, two disciples walking into the country — and lastly to eleven witnesses, the eleven apostles all assembled together. Let us remember, in addition to this, that other appearances of our Lord are described by other writers in the New Testament, beside those mentioned by Mark. And then let us not hesitate to believe, that of all the facts of our Lord's history, there is none more thoroughly established than the fact, that He rose from the dead. There is great mercy in this. The resurrection of Christ is one of the foundation-stones of Christianity. It was the seal of the great work that He came on earth to do. It was the crowning proof that the ransom He paid for sinners was accepted, the atonement for sin accomplished, the head of him who had the power of death bruised, and the victory won. It is well to remark how often the resurrection of Christ is referred to by the apostles. "He was delivered for our offences," says Paul, "and was raised again for our justification." (Rom. 4:25.) "He has begotten us again to a living hope," says Peter, "by the resurrection of Jesus Christ from the dead." (1 Peter 1:3.) We ought to thank God that the fact of the resurrection is so clearly established. The Jew, the Gentile, the priests, the Roman guard, the women who went to the tomb, the disciples who were so hesitant to believe, are all witnesses whose testimony cannot be gainsaid. Christ has not only died for us, but has also risen again. To deny it shows far greater credulity than to believe it.

He appeared in another form - In a form unlike his ordinary appearance so much so that they did not at first know him. See the notes at Luke 24:13-31. “As they walked and went into the country.” To Emmaus, Luk 24:13.
