You know? I have heard Dr. Ergun Caner preach 3 times. He is gifted, to say the very least. But to hear him speak of how a Muslim has no certainty of their eternity is bone chilling. When they come to the end of their life, if their good deeds outweigh their bad deeds then they will go to heaven. The only way to erase the bad deeds is by becoming a martyr.
This is in stark contrast to Christianity where one receives eternal life as a gift from God through faith in Jesus Christ.
