Worry and anxiety rob us of SO MUCH - it’s tragic! That’s why God tells us many times and many ways in the Bible not to do this. He knows how it affects us, even tortures us - and it’s not reality. And it’s definitely not faith. The Lord wants to help, though, by giving us a deep peace that guards our hearts and minds.
“Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God’s peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus.” Philippians 4:6-7
Why wouldn’t we do this instead of worrying - not in addition to it?
