Wow, the best Bible verse on this is: Isaiah 56:7 I will bring them to My holy mountain, And make them joyful in My house of prayer. Their burnt offerings and sacrifices will be accepted on My altar; My house shall be called a house of prayer for all nations.
Notice, it is a house of prayer, not a prayer room, not a place of prayer. A house is a place where we live and are comfortable. We typically live in our house almost everyday. Um, everyday is about how often we should pray.
