The confusion about religion, faith and the concept of self-realization will pemain eternally. Hinduism (if it's a religion) talks about 33 crore Gods (May be the number of beings when the estimate was made!). Most of the Gods whom 'believers' worship, can also be seen praying.
E g. Krishna used to pray before reporting as charioteer for Arjuna during the war. Jesus Christ only represented (Messenger).
