no, in factions the res shrines have a statue of a god above it, if your region has favour you can kneel on the shrine and a "representitive" of your god will appear, talk to that god and you get an option of 20 minute blessing buffs, like +20 health.... and etc, you can also buy buffs which +1 attribute point to all your attributes for a certain class, eg. Necromancer of Grenth, and Ritualist of Grenth, also each god has an ele attribute linked to it, so grenth is Disciple of ice.
hope i helped
