To them it was revealed, that not to themselves, but to you, did they minister these things, which now have been announced to you through those who preached the Gospel to you by the Holy Spirit sent out from heaven; which things angels desire to look into.
It was shown to them that their service was not for themselves. It was for you. They were serving you when they told about the truths you have now heard. The men who preached the Good News to you told you those things. They did it with the help of the Holy Spirit that was sent from heaven. These are truths that even the angels want very much to know about.
