Please read American Pastor Imprisoned in Iran Told to Deny Christ, by Heather Clark, at persecution.org.
"Pastor Saeed Abedini, an American citizen imprisoned for his Christian faith in Iran, was given an ultimatum to either deny Christ or remain incarcerated. Saeed Abedini, an American Pastor in Iran, has been sentenced to eight years in prison in Iran for planting house churches. He says that the officials have given him the choice to deny Christ or remain in prison. The ACLJ has obtained a recent letter from Saeed, which describes the stress and pressure he is facing in prison: “‘Deny your faith in Jesus Christ and return to Islam or else you will not be released from prison. We will make sure you are kept here even after your 8 year sentence is finished.’ These are the threats that prison officials throw at me. My response is Romans 8:35-39.”
