When I first heard this reason for the trustworthiness of the Gospel, I thought to myself that there are other religions that have adherents who suffer and die for their faith. Surely many Muslims have no problem letting themselves be killed for their faith. But I was quickly corrected in regards to what this really meant.
Muslims have died for what they believed to be true, but the early Christians died for what they knew was true. There really is a huge difference. The early Muslims took Muhammad at his word when he told them that Gabriel had spoken to him. However, the early church was there when Jesus performed his miracles, when he fed the 5,000, when he gave the blind back their sight, when he walked on water, when he raised people from the dead, when he rose from the dead and appeared to over 500 people at once, and even when he ascended in Acts 1.
If the message of the early church was a pure fabrication, we would have found out the moment that first stone was thrown, because no one dies for something they know is a lie. Instead these men died knowing what they had seen was true and even lead the first recorded martyr after Christ's death, Stephen to say these words right before he himself was thrown from the city and stoned to death. "Behold, I see the heavens opened, and the Son of Man standing at the right hand of God." (Acts 7:56)
Read the following accounts of persecutions and executions of early church members:
These men died not for what they thought or heard, but for what they had seen and experienced with their very own eyes. This is entirely different from those who believe based off what one man tells them like in Islam, Mormonism, Jehovah's Witnesses, Buddhism, and pretty much every other religion in existence. These men either died for what they knew to be true, or they died for a lie; and no one dies for something they know is false.
