=Thy will be done on earth, as it is in heaven.=
_That is_,
The good and gracious will of God is done indeed without our prayer;
but we pray in this petition that it may be done also among us.
This is done when God brings to nothing all evil plans and purposes of
the devil, the world, and our own flesh, that would hinder the
hallowing of His name and the coming of His kingdom.
On the other hand, it is the good and gracious will of God to strengthen
us and keep us steadfast in His Word and in faith, until death.
