The exiles of the Dispersion were privileged to hear of the glorious progress in the history of redemption that God had permitted to happen in the life and death of Jesus of Nazareth. That puts them in a richer place than the prophets (and their hearers) of long ago. They could only “search” and “inquire” about the details of the glories hinted at in their prophecies. In contrast, the exiles of the Dispersion got to hear about the Son of God actually becoming man, living our kind of (broken) life, going to the cross as the Lamb of God to atone for sin, majestically arising from death as evidence he paid for sin, triumphantly ascending into heaven, and pouring out his Spirit upon sinners. In a word, those exiles received “salvation!” So they were so much more privileged than the prophets of the Old Testament had been.
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.
