The Second Petition.
What does this mean?–Answer.
The kingdom of God comes indeed without our prayer, of itself; but we pray in this petition that it may come unto us also.
How is this done?–Answer.
When our heavenly Father gives us His Holy Spirit, so that by His grace we believe His holy Word and lead a godly life here in time and yonder in eternity.
Martin Luther, The Small Catechism
