Albert Barnes Commentary Luke 24:45

"Then opened he their mind, that they might understand the scriptures;" — Luke 24:45 (ASV)

He opened their understanding. He enabled them to fully comprehend the meaning of the prophecies that foretold His death and resurrection. They had seen Him die; they now saw Him risen. Their prejudices were now removed by His instructions and by the facts which they could no longer call in question. Consequently, they no longer doubted that He was the Messiah, and that all the facts in the case that had previously confounded them could be easily accounted for. Hence we may learn:

1. That facts, or the further disclosure of truth, will yet remove the mysteries that we now see in religion.
2. That our prejudices and our preconceived opinions are one cause of our seeing so many mysteries in the Bible. If a man is willing to take the plain declarations of the Bible, he will commonly be little perplexed with mysteries.
3. That God only can open the mind so as fully to comprehend the Scriptures. He only can overcome our prejudices, open our hearts, and dispose us to receive the ingrafted word with meekness, and with the simplicity of a child. (James 1:21; Mark 10:15).
4. That the design of God's opening the understanding is that we may be acquainted with the Scriptures. It is not that we may be made wise above what is written, but that we may submit ourselves wholly to the Word of God.
