Some people find it very hard to believe that salvation and spiritual growth can occur outside their religion. 

Enoch and Elijah were not Christians, Muslims, Hindus, etc. Elijah may have practiced Judaism but definitely not Enoch. 

These two men grew in faith, in love, in intelligence and spirituality to such an extent that they qualified to ascend to heaven without even tasting death! 

It's not about evolutionary, man-made religion. It's about walking in the spirit, manifesting the fruits of the spirit. It's about personal, conversational relationship with God.
