(Read the series so far.)
The book of Hebrews enhances our understanding by detailing two periods in human history in which the Lord has spoken to mankind. Hebrews 1:1 proclaims that the first period was “long ago to the fathers and prophets in many portions and in many ways.” This is an obvious reference to the revelations given during the times of the Old Testament. In verse two the author of Hebrews cites the second period of divine revelation by simply saying that “in these last days [God] has spoken through His Son.” But as we know, Jesus Himself did not write down anything that He said. That was left to His followers and so, the author of Hebrews adds: “After it was first spoken through the Lord, it was confirmed to us by those who heard” (Heb 2:3) i.e. the apostles.
This, however, raises a practical problem. How did the people know that the communication they were receiving from the apostles was true? After all, many individuals made claim to being an apostle during the first century. The Lord would authenticate His true apostles by giving them the ability to perform “signs and wonders, and by various miracles and by gifts of the Holy Spirit” (Heb 2:4). When the Corinthians challenged Paul’s apostleship and authority, he pointed them to the “signs of a true apostle … [which were] signs and wonders and miracles” (2 Cor 12:12), just as the author of Hebrews confirmed.
