Religion is not an end in itself. One's union with God is the ultimate goal. There are so many religions because immature people tend to emphasize trivial differences instead of important likenesses. Differences between faiths lie in creeds and rituals rather than religious principles.
How diverse the many paths seem to be at times, but do they not all come together eventually upon the same mountaintop? Are they not all striving for the same thing? If you are guided toward a faith, use it as a stepping stone to God, not as a barrier between yourself and God's other children or as a tower to hold you aloft from others. If you are not guided toward a faith (or even if you are) seek God in the silence -- seek within.
When we attempt to isolate another we only isolate ourselves. We are all God's children and there are no favorites. God is revealed to all who seek; God speaks to all who will listen. Be still and know God.
