Islam is pretty easy to debunk. Muslims claim that Christians and Jews can also be saved from Hell, which is caused by sin. However, what is sin? Sin is a rejection of God, who is truth. If Islam is the full truth, then Christians and Jews are sinning against God and cannot possibly be saved. Also, if Christianity and Judaism was already saving souls, then what was the need for Mohammed? Christianity is the only religion in the world to claim absolute exclusivity. Jesus Christ is also the only person in the history of humanity to have risen from the dead after 3 days. Jesus is the only person in the history of humanity to garunttee forgiveness of sins and heaven to those who follow Him. Mohammed didn't garaunttee anything, he said no one knows if they're saved, hence the reason why muslims pray for Mohammed. Muslims do not know who they worship, they just worship some abstract concept that they call "Allah." However, Christians do know who they worship, His name is Jesus Christ. Jesus died for us on the cross. What did the "deities" and "prophets" of other religions do for us?
