“Lord’s Prayer,” Sue Bergin, Encyclopedia of Mormonism
We are to follow Christ’s example in all things, including the way in which He prays. Jesus counsels his listeners to not recite his prayer but to pray “after this manner.” By using the Lord’s Prayer as a framework, and by expressing personal, heartfelt feelings, true unity with God the Father can be found.
