When we are persecuted for the cause of Christ, we will receive a great reward in heaven  -  Matthew 5:11-12

Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake. Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.

If we are persecuted for Christ’s sake, we will receive a reward. Christ knew that if we are His disciples and are loyal to Him, we will face persecution. The reward that is received because of persecution is not specified but it will be great.
