I'm sure many of you also struggle occasionally with worry. I think it comes when we forget to leave things in God's hands and try to wrangle everything on our own, even though we can't. We weren't meant to. It can be a difficult thing to overcome, but its not impossible. Some verses I remember when I'm feeling stressed and worried:
Who of you by worrying can add a single hour to his life?
Do not worry about anything. Instead in everything by prayer and petition, with thanksgiving, present your request to God. And the peace of God which transcends all understanding will guard your hearts and your minds in Christ Jesus.
Worry is so difficult to overcome, especially for me, but with God it is possible. As hard as it is, we need to remember to surrender our worries to him.
