God is the name of our believe only.God is of so kind heart that it always keeps the honor of our believes.Suppose if we believe on a Stone and think that the God is in this stone,may be the God does not exist in the stone,but to honor your believe it become so as you wish about the God.We think that if we collect the water from the holy river Ganjes in a pot and after hiking 100Kms on difficult path continuously, if we pour the water of the river Ganjes on the God Shiva's Ling (i.e. idol/stone assumed to be the God) then your desire will be full filled ,then the God will certainly honor your believe by fulfilling your desire.
However the God is available equally everywhere whether it is a temple or mosque or nothing, omnipresent,invisible.
So seekers of God are advised to go for easy worship of the God ,without torturing our bodies ,because the God loves us and our bodies more than we ourselves,to avoid giving pain to the kind hearted God,if we really love the God.
