The devil's will and purpose and all our enemies shall and must fail...

We have this comfort and confidence: the devil's will and purpose and all our enemies shall and must fail and come to nothing, no matter how proud, secure, and powerful they know themselves to be.  For if their will were not broken and hindered, God's kingdom could not remain on earth nor His name be hallowed.

The eternal inestimable treasure in God's kingdom come to us...

From this you can see that we do not pray here for a crust of bread or a temporal, perishable good.  Instead, we pray for an eternal inestimable treasure and everything that God Himself possesses.  This is far too great for any human heart to think about desiring, if God had not Himself commanded us to pray for the same.  But because He is God, He also claims the honor of giving much more and more abundantly than anyone can understand.  He is like an eternal, unfailing fountain.  The more it pours forth and overflows, the more it continues to give.

His Kingdom comes both here in time and in eternity...

His kingdom comes of itself, without our prayer.  Yet we still pray that it may come to us, that is, triumph among us and with us, so that we may be part of those people among whom His name is hallowed and His kingdom prospers....For the coming of God's kingdom happens in two ways: (a) here in time through Word and faith and (b) in eternity forever through revelation.
