Charles Spurgeon Commentary 1 Peter 4:13-14

"but insomuch as ye are partakers of Christ`s sufferings, rejoice; that at the revelation of his glory also ye may rejoice with exceeding joy. If ye are reproached for the name of Christ, blessed [are ye]; because the [Spirit] of glory and the Spirit of God resteth upon you." — 1 Peter 4:13-14 (ASV)

But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy. If ye be reproached for the name of Christ, happy are ye; did not your Savior say, "Blessed are ye, when men shall hate you, and when they shall separate you from their company, and shall reproach you, and cast out your name as evil, for the Son of man's sake. Rejoice ye in that day, and leap for joy: for, behold, your reward is great in heaven: for in the like manner did their fathers unto the prophets."

So, be glad about it.
