What the Prophets Discovered

1 Peter 1:12

12 It was revealed to them that they were not serving themselves, but you, in these things which now have been announced to you through those who preached the gospel to you by the Holy Spirit sent from heaven — things into which angels long to look.

In their search they concluded that their words were written not for their own benefit but for those far in the future—for us. And they were announced to us through those who preached the gospel by the Holy Spirit. This wonderful gospel of grace certainly has had the attention of the angels. 

The Prophet’s Predictions of Christ

1 Peter 1:10-11

10 As to this salvation, the prophets who prophesied of the grace that would come to you made careful searches and inquiries, 11 seeking to know what person or time the Spirit of Christ within them was indicating as He predicted the sufferings of Christ and the glories to follow.

The Old Testament Prophets prophesied of the coming Christ and of His grace, yet they had no clear understanding of it—because it was so far in their future. So, they made careful study and inquiries of their own prophetic words in order to understand the Spirit of Christ within them, speaking to them about how He would suffer and then also be glorified (look at Isaiah 52:14-15; 53:1-7; 61:1-3).
