In the Koran, it very specifically says to kill infidels, and I can ask my dad for the reference. (We have a copy.) In the Bible, we all know "Thou shalt not kill", and 1 John 3:15a says "Whosoever hateth his brother is a murderer" Muslims believe that Allah never had a son. Christians base their beliefs on the Son of God, the Messiah. Jews believe the Messiah hasn't come yet.Muslims' 'paradise' is a big party, with booze and women galore. Christians 'heaven' is eternal fellowship with God and other believers, with no more pain and suffering, and no more evil.
