Faith means to have a firm belief in something for which there is no proof.

Religion is the practice or the service and worship of God or the supernatural; a commitment or devotion to religiious faith.

Spirituality is one's connection with God.

Faith comes through being in a continuous state of learning about God. The more you learn, the more Truth is exposed, then Faith grows through the supernatural proof of what one knows about God. This learning and growing, practicing and holding fast to the tennets of any faith is what is called religion.
