“Although the words spoken through the prophets are difficult at times to comprehend, sometimes this is because their primary purpose may be for a particular situation which has not yet occurred. Prophecy is often intended for future generations to understand after the events have taken place to which the prophecy is pointing. This was the case with many Old Testament prophecies, particularly to those that pointed forward to the coming of Christ. Peter writes in 1 Peter 1:10-12 regarding the salvation brought to mankind through Christ, ‘Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care, trying to find out the time and circumstances to which the spirit of Christ in them was pointing when he predicted the sufferings of Christ and the glories that would follow. It was revealed to them that they were not serving themselves but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.’
He is saying that there are truths found in Scripture that the prophets themselves did not understand because they pertained to future events to which they were not entirely privy, but which are now available to us through the gospel. In fact, even angels long to probe these prophecies more fully, since they are so rich and deep.” (Edwin Reynolds, Accurately Handling the Word of Truth, art. 2004, The Word of God, p.15)
