If Christianity is available only to the humblest of people, to what kind of people is Judaism, Mormanism, and Hinduism available?
Mormonism and Hinduism were not designed by the God of the Bible. They are religions in direct conflict with and completely incompatible with the God of the Bible. The world is full of false religions. The God of the Bible continually describes Himself as "a jealous God" who permits no false religions. The God of the Bible destroyed many civilizations because of false religion.
Judaism is of God and was created for a certain, small group of people for the express purpose of birthing the Messiah, who would then reconcile the entire world to God. The entire Old Testament points to the coming Messiah, via the many prophesies about Him, (where He would be born, WHEN He would be presented as King of the Jews, etc).
Jesus, a Jew, is the Messiah that the entire Jewish race and religion was created by God to nurture, and give birth to, and present to the world.
