Your will be done on earth as it is in heaven.
The good and gracious will of God is done indeed without our prayer; but we pray in this petition that it may be done among us also.
How is this done?–Answer.
When God breaks and hinders every evil counsel and will which would not let us hallow the name of God nor let His kingdom come, such as the will of the devil, the world, and our flesh; but strengthens and keeps us steadfast in His Word and in faith unto our end. This is His gracious and good will.
Martin Luther, The Small Catechism
