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.
