Just another piece of Evangelical lingo that sounds good, but isn’t really scriptural.
1 Peter 5:7 casting all your care upon Him, for He cares for you.
Philippians 4:6 Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; 7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
