John - 12:36 Meaning
“While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.”
King James Version (KJV)
Matthew Henry's Concise Commentary
12:34-36 The people drew false notions from the Scriptures, because they overlooked the prophecies that spoke of Christ's sufferings and death. Our Lord warned them that the light would not long continue with them, and exhorted them to walk in it, before the darkness overtook them. Those who would walk in the light must believe in it, and follow Christ's directions. But those who have not faith, cannot behold what is set forth in Jesus, lifted up on the cross, and must be strangers to its influence as made known by the Holy Spirit; they find a thousand objections to excuse their unbelief.
“And it shall come to pass in that day, that the mountains shall drop down new wine, and the hills shall flow with milk, and all the rivers of Judah shall flow with waters, and a fountain shall come forth of the house of the LORD, and shall water the valley of Shittim.”
