When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.
All Commentaries on 2 Thessalonians 1:10 Go To 2 Thessalonians 1
John Chrysostom
AD 407
Is God glorified? Yea, he says, in all the Saints. How? For when they that puff so greatly see those who were scourged by them, who were despised, who were derided, even those now near to Him, it is His glory, or rather it is their glory, both theirs and His; His indeed, because He did not forsake them; theirs, because they were thought worthy of so great honor. For as it is His riches, that there are faithful men, so also it is His glory that there are those who are to enjoy His blessings. It is the glory of Him that is good, to have those to whom He may impart His beneficence. And to be marveled at, he says, in all them that believed, that is, through them that believed. See here again, in is used for through. For through them He is shown to be admirable, when He brings to so much splendor those who were pitiable and wretched, and who had suffered unnumbered ills, and had believed. His power is shown then; because although they seem to be deserted here, yet nevertheless they there enjoy great glory; then especially is shown all the glory and the power of God. How?
Because our testimony unto you was believed in that day.
