Giang A Ca, a North Vietnam Hmong tribesman, was sentenced to three years imprisonment (1997). He was released early after thousands of letters poured into the country on his behalf from Christians around the world. Out of gratitude for this "good work," Giang volunteered to go back to prison to gather information on other prisoners and witness to his Lord and Savior from behind bars. He is once again a prisoner, bringing to completion the vital importance of sharing the gospel, defending it against those who would imprison it, and confirming it for those who are imprisoned because of it.
