Matthew 6:34 Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.

God will take care of his own people. He has not always be very tender with them. To educate and test them, he has put terrible challenges and choice before them Just consider this verse: 2 Kings 6:28
Then he asked her, “What’s the matter?” She answered, “This woman said to me, ‘Give up your son so we may eat him today, and tomorrow we’ll eat my son.’  Isn't that a terrible verse? A verse that seems to contradict all human feeling? But then, do we know who we'd be tomorrow, if that morrow brings mourning and sorrow? If it brings hunger so vast, that mothers think about eating their own children in order to survive. 

Can you be sure, what tomorrow will be made of? To many it is only more of the same. More work, more washing, more cooking, more driving, more yelling and being yelled at. And so on. If there is no peace between me and God today, tomorrow brings no new hope, as much as I'd like it to be.

But those who have found peace with God, even in the midst of terrible temptations they can lean back and not worry about tomorrow. For with the challenge God will bring new ways to get by. To get a little closer to heaven. Not only tomorrow. Today.
