This explains why the Lord’s Prayer is short, direct, and relatively straightforward in its language. God already knows what you’re going to ask of him, so be brief and to the point, Jesus says. The context in which the fullest and most famous version of the Lord’s Prayer appears in the Bible is in Jesus’ Sermon on the Mount, where he specifically cautions against using pointless repetitions in prayer, just for the sake of making lots of words and noises for God.
