God is as an eternal fountain that gushes forth abundantly nothing but what is good...

We are to trust in God alone and look to Him and expect from Him nothing but good, as from one who gives us body, life, food, drink, nourishment, health, protection, peace, and all necessaries of both temporal and eternal things.  He also preserves us from misfortune.  And if any evil befall us, He deilvers and rescues us.  So it is God alone (as had been said well enough) from whom we receive all good and by whom we are delivered from all evil. ...It is as though He were an eternal fountain that gushes forth abundantly nothing but what is good.  And from that fountain flows forth all that is and is called good.

Even though we experience much good from other people, whatever we receive by God's command or arrangement is all received from God.  For our parents and all rulers and everyone else, with respect to his neighbor, have received from God the command that they should du us all kinds of good.  So we receive these blessings not from them, but through them, from God.  For creatures are only the hands, channels, and means by which God gives all things.  So He gives to the mother breasts and milk to offer to her child, and He gives corn and all kinds of produce from the earth for nourishment.  None of these blessings could be produce by any creature of itself.

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.

Every mote of our existence is from God...

For although the whole world should work together, it could not add an hour to our life or give us a single grain from the earth.

God overwhelms us with unspeakable, eternal treasures...

From here we see how the Father has given Himself to us, together with all creatures, and has most richly provided for us in this life.  We see that He has overwhelmed us with unspeakable, eternal treasures by His Son and the Holy Spirit, as we shall hear.
