This is a pretty well known verse, but a good one that should be written on our hearts. Money is a big thing we worry about, but what about all the little ones that consume us. I am a planner and so when I see my calendar full of things coming up and food I need to make, presents that need to be bought, I get a little big anxious about it all. Sometimes we forget that our worry is sin. If you have a problem with worrying I suggest to you that you might want to memorize this verse.
Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble. Matthew 6:34
