Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on My account. Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you.—Matthew 5:11-12
Being mistreated for following Jesus is a blessing. Jesus tells us to rejoice and be glad when that happens. We receive a great reward in heaven.
There is no blessing if we suffer for doing evil, but if any of us suffers as a Christian, we should not be ashamed but should glorify God in that Name (1 Peter 4:15-16). That is how the early Christians in Jerusalem reacted when they were arrested and beaten for speaking in the Name of Jesus (Acts 5:40-41). They rejoiced that they were counted worthy to suffer dishonor for the Name.
We are blessed when we are persecuted or lied about because of Jesus. He tells us to rejoice and be glad when that happens.
