“’Blessed are they who are persecuted for righteousness’ sake for theirs is the kingdom of heaven. Blessed are you when men revile you, and persecute you and utter all kinds of evil against you falsely for my sake’ (Mt. 5.10-11). In saying these words, Christ promised that those who would follow Him would certainly be persecuted. This is a central prediction of the Gospel and an essential condition of those who accept it.
‘Remember the word that I said to you, “A servant is not greater than his master.’” If they persecute me, they will persecute you; if they have kept my word, they will keep yours also. But all this they will do to you on my account, because they do not know Him who sent me.’ (Jn 15.20-21).
True Christians will always be persecuted for Christ’s sake. They will be persecuted with Christ and like Christ, for the truth that they speak and the good that they do. The persecutions may not always be physical, but they will always be spiritual and psychological. They will always be mindless, unjust, violent, and “without cause” (Ps 69.4, Jn 15.25). They will always be painful and the cause of much suffering. For ‘indeed all who desire to live a godly life in Christ Jesus will be persecuted’ (2 Tim 3.12).
A person embarking on the spiritual life must expect persecution and slander. He must be wary, however, of any false persecution complex, and must be absolutely certain that the suffering he meets is solely ‘for righteousness’ sake’ and not because of his own weakness and sins.” (Thomas Hopko, Vol. 4 Spirituality, p. 50)
