Q.107: What does the preface of the Lord’s Prayer teach us?
A. The preface of the Lord’s Prayer, which is Our Father which art in heaven, teaches us to draw near to God with holy reverence and confidence, as children to a father, able and ready to help us; and that we should pray with and for others.
In this manner, therefore, pray: Our Father in heaven, Hallowed be Your name. Matthew 6:9
