1 Peter 1:10-12 (ESV)

10 Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully,

11 inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and the subsequent glories.

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