But rejoice, inasmuch as ye are partakers of Christ’s sufferings - That is, sufferings of the same kind that he endured, and inflicted for the same reasons. Compare Colossians 1:24; James 1:2; See the notes at Matthew 5:12. The meaning here is, that they were to regard it as a matter of rejoicing that they were identified with Christ, even in suffering. See this sentiment illustrated at length in the notes at Philippians 3:10.
That, when his glory shall be revealed - At the day of judgment. See the notes at Matthew 26:30.
Ye may be glad also with exceeding joy - Being admitted to the rewards which he will then confer on his people. Compare 1 Thessalonians 2:19. Every good man will have joy when, immediately at death, he is received into the presence of his Saviour; but his joy will be complete only when, in the presence of assembled worlds, he shall hear the sentence which shall confirm him in happiness forever.
