Jesus was an itenerant teacher/preacher, going around telling large groups of people parables intended to show them a more loving way of living. One of his disciples followed him up a hillside one day and asked him to teach him how to pray to God as he did himself. Jesus shared a format for prayer, not some dogma that should be followed exactly by every group every time they get together for more than 2,000 years. So many people forget to think for themselves, eh?

Yes, it's in the bible, Matthew 6: 9-13. Also Luke 11: 2-4.
