Jews and Christians worship God. Muslims do worship one thing, but it isn't God.
Actually, Jews and muslims worship the same god. Christians worship another. Take those words specifically spoken by Christ, not editorials, letters from Paul to Greeks, Syrians or Regis Philbin and Revelations, you will see He splits from the Torah, Talmud, Saducees and Pharisees at every possible juncture.
Nonsense.
Do you have a copy of the Old Testament with the Koran glued to it somewhere?
Do you have a copy of the New Testament lacking Hebrews?
Boy I'll bet the Jews appreciate that for thousands of years they have worshipped a moon God that seeks their extermination as a race!
Paul received his revelations directly from Christ.
Christ opined on Islam 600 years before its existence?
There is more difference among Christian sects than there is between Jews and Christians. You probably call yourself a Christian. Do you handle poisonous snakes during rites? Are you married to multiple wives? Do you forsake secular health care for spiritual belief? Are you a teetotaler? Are you obsessed with Jews as Christ killers? Are you obsess with saving the Jews and the Holy land? A Christian has a lot of options to be very different.
