The sermon is based on Philippians 4:4-7 (CEB)
4 Be glad in the Lord always! Again I say, be glad! 5 Let your gentleness show in your treatment of all people. The Lord is near. 6 Don’t be anxious about anything; rather, bring up all of your requests to God in your prayers and petitions, along with giving thanks. 7 Then the peace of God that exceeds all understanding will keep your hearts and minds safe in Christ Jesus.
