I can't recommend enough the series Beth Moore did on Trusting God on the Life Today show last year. You can find it here. Just scroll down until you see "Who do you trust?" And you can watch or listen to it online for free.
Please take the time to listen through this series if you are having problems with worry, or an aching heart over concern for something in your life. Beth does a wonderful job of mapping out mistrust, and how that leads to a spinning mind and an ailing, aching heart that keeps us stuck in worry.
Plus, she's her funny, sweet self as usual. :)
Check it out today. I listen to it while I'm working, so even if you can't sit and watch you can listen. I'm giving it about my fourth listen here today, and each time it gives me new encouragement.
"The very area where you are most tempted to distrust God is the very place He has most chosen to trust you." -Beth Moore
Blessings on your day, ladies!
