Faith is the system by which an individual can gain entry into the Heavenly Abodes. Paying tribute to a deity does not qualify as faith. The only way to gain faith is to actually build a relationship with your deity and go the extra way to appease them. Perform pilgrimages, live your life in their name and erect places of worship for your deity. Upon physical death, if you have gained your deity's trust, you will spend the next few centuries in the Heavenly Abodes alongside them and other faithful worshipers.
