"Give us this day our daily bread" (Mt.6:11).
Just as you can't eat tomorrow's breakfast today, neither can you pray tomorrow's prayers in advance.
You have to look to the Lord one day at a time.
God has designed the world so He'd give us the grace we need day by day.
And this is a good thing... otherwise we'd seek to carry out whatever He calls us to do without Him... which would surely end up badly.
Put another way... God has set things up so we must depend on Him daily for our sanity and success.
