Unto whom it was revealed, that not unto themselves, but unto us they did minister the things, which are now reported unto you by them that have preached the gospel unto you with the Holy Spirit sent down from heaven; which things the angels desire to look into.
All Commentaries on 1 Peter 1:12 Go To 1 Peter 1
Clement Of Alexandria
AD 215
Of ineffable and unutterable blessings, which eye hath not seen, nor ear heard, nor have entered into the heart of men; into which angels desire to look, and see what good things God hath prepared for the saints and the children who love Him."
