But if one of you suffers for being a Christian, let him not be ashamed; but let him glorify God in this matter.
let him not be ashamed: Some suffering is disgraceful and should cause a person to be ashamed. Suffering as a murderer, or a thief, or as evildoer, or as a meddler is a shame. Suffering for such things is deserved (1 Peter 2:14).
