You do know Christianity, Judaism and Islam all inherited and share Abrahamic religious roots, as outlined in the Old Testament? They all believe in Abraham and Moses, they all believe in Paradise (Heaven) after death, they all espouse the same values as described in the Old Testament, from honouring thy mother and father to avoiding eating pork and alcohol, well, not the Christians, who also differ in that they believe in the Holy Trinity, Islam and Judaism only believe in one God. Christians also differ in that they practice idolatry.
Point is, they all share the same religious heritage from Abraham.
You have way more in common with Jews and Moslems than you think. Especially if you are a Christian.
I think you meant, but do not wish to post it, that the difference of Judaism, Christianity and Islam is how they individually view Jesus. Those who are Jewish are still waiting for God's promise savior and those who are Muslim look to works and proper living as a savior. However, Christians know Jesus to be the savior God promised, I.e. the Savior promised in the O.T.
Yes, there are people who practice idolatry but also those that practice paganism/satanism, however, a person whom does so is not a christian in reality.
On a separate issue, Jews and Moslems do NOT share the same heritage of Abraham. The O.T. speaks of the promise made to Abraham AND to his wife Sarah.
Only the children of Abraham AND Sarah, according to the O.T., are covered by this promise of God.
