Hebrews 1:1-2a says, “Long ago, at many times and in many ways, God spoke to our fathers by the prophets, but in these last days he has spoken to us by his Son...”
In his commentary on Hebrews, F. F. Bruce argues that we should understand the phrase “in these last days” as a Hebraism that means, “in the days when the words of the prophets are fulfilled.” For evidence of this position he sites Genesis 49:1, Numbers 24:14, Deuteronomy 4:30, 31:29, Isaiah 2:2, Jeremiah 23:20, 30:24, 48:27, 49:39, Ezekiel 38:16, Daniel 10:14, Hosea 3:5, and Micah 4:1 (The Epistle to the Hebrews, Grand Rapids: Eerdmans Publishing Company, 46, fn 14).
He makes a compelling case, although we must leave room for the likelihood that these first century Christians may have expected Jesus to return in their lifetimes. Whatever the case may be, we are on safe biblical grounds to interpret the phrase to mean “the time between the first and second comings of Jesus wherein the words of the prophets were fulfilled.”
