Philippians 4: 6-7 ESV
“Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.”

Anxieties,worries, fears, things we cannot fix or change, when we give them to God and thank Him, He will give us a strong peace so that cause us to trust Him that He will do what is best for us. Maybe not exactly the way we may want things to happen but He will take care of each and everything we give Him.
