What we call the "Lord's Prayer" is the prayer Jesus taught to his disciples.
If we can't pray it sincerely ourselves, we can ask Jesus to pray the prayer in us.
Unable to grasp God's essence, we seek help in words, in names, in animal forms, in figures, in trees and flowers, summits and sources. (Maximus of Tyre)
The prayer of the humble pierces the clouds,
and it will not rest until it reaches its goal.
(Sirach 35:21)
