Philippians 4:6–7 (NIV)
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Do not be anxious anything when you believe in God.
Pray or talk to God, He is there to listen to you, surrender all you anxious thought to the Lord.
