Although what we most often refer to as “the Lord’s Prayer” is certainly appropriate to pray any time, it seems Jesus intended that it be prayed in the morning. The evidence for that is the line, “Give us this day our daily bread” (Matt. 5:11). That would seem more appropriate to pray at the beginning of the day rather than at the end. That line also leads us to think that “the Lord’s Prayer” was meant to be a daily prayer.
The reason I’m also claiming it is a perfect prayer is because it was given to us by a perfect Person, and it contains seven requests. You probably know that, in the Bible, seven is the number of perfection.
