Hamid Pourmand is a Colonel in the Iranian army where it is not a welcomed thing to be a Christian. Another piece to the puzzle is that Colonel Pourmand is an officer in an army that is forbidden by law to have officers who are non-muslims.
The Muslims are jealous. The story states:
During the hearing, court officials declared that for many years Pourmand had belonged to an ‘underground’ church through which “many Muslims” had deserted Islam and become Christians.
May the Lord be his strength and fortress!
