The Lord Himself has taught us how to pray
Perhaps there is no prayer uttered more often by Christians than the Our Father. And there is good reason for this frequency, because Jesus himself taught it to his disciples when they asked him how they were to pray (see Matthew 6:9-13 and Luke 11:2-4).
From the early days of the church, the Lord's Prayer has occupied a special place in the life of Christians. The second-century Didache, one of the earliest Christian documents outside the New Testament, commanded that the Our Father should be said by Christians three times a day.
