Our heart burn within us - This is an expression denoting the deep interest and pleasure which they had felt in his discourse before they knew who he was. They now recalled his instruction; they remembered how his words reached the “heart” as he spoke to them; how convincingly he had showed them that the Messiah ought to suffer, and how, while he talked to them of the Christ that they so much loved, their hearts glowed with intense love. This feeling was not confined to them alone. All the followers of Jesus know how precious and tender are the communications of the Saviour, and how the heart glows with love as they think or hear of his life, and sufferings, and death.
He opened to us - He explained to us the Scriptures. See Luke 24:27.
This narrative shows us,
1. How blind people may be to the plainest doctrines of the Scriptures until they are explained to them. These disciples had often read or heard the Scriptures, but never, until then, did they fully understand that the Messiah must suffer.
2. It is proper there should be those whose office it is to explain the Scriptures. Jesus did it while on earth; he does it now by his Spirit; and he has appointed his ministers, whose business it is to explain them.
3. If people attempt to explain the Bible, they should themselves understand it. They should give their time and talents to a suitable preparation to understand the sacred volume. Preaching should consist in “real,” and not “fancied” explanations of the Scriptures; the real doctrines which “God” has taught in his word, and not the doctrines that “men” have taught in their systems.
4. Here was convincing evidence that Jesus was the Messiah. This was but one of many instances where Jesus convinced his disciples, contrary to their previous belief. In this case the evidence was abundant. He first satisfied them from the Old Testament that the very things which had happened were foretold; he then dissipated every doubt by showing “himself” to them and convincing them that he was truly the Christ. There was no chance here for deception and juggling. Who would have met them and talked with them in this way but the real Saviour? Who would have thought of writing this narrative to help an imposture? What impostor would have recorded the dulness of the disciples as to the plain declarations of the Old Testament, and “then” have thought of this device to prop up the narrative? Everything about this narrative - its simplicity - its tenderness - its particularity - its perfect nature - its freedom from all appearance of trick - shows that it was taken from real life; and if so, then the Christian religion is true, for here is evidence that Jesus rose from the dead.
