Christians probably look at other religions as others look at Christianity.

Keeping it simple, God is too big for one religion.  God lets God's being be known as we as humans from different cultures, upbringings, countries, and intelligence allows.

I was raised in a Protestant Christian church, but after reading much Christian philosophy and theology, I converted to Roman Catholicism more than 30 years ago.  It is an extension of Christianity's Jewish theology.  Judaism makes is understandable and richer in Tradition that the Holy Catholic Church.  I may one day convert to Judaism.

I've taken college course of other religions.  Eastern religious thought is not right for me.  I believe that is what is intended.  Islam is also very rich in Tradition and appealing to me.  I also believe it is not intended for me.

One day, I hope to really understand God's puzzles before, "in the sleep of death, what dreams may come when we shuffled off this mortal coil."
