Philippians 4:6-7
6 Do not be anxious about anything but in everything, by prayer and petition, with thanksgiving present your request to God.7 And the peace of God which transcends all understanding will guard your hearts and minds in Christ Jesus.
โTherefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.โ
2 Corinthians 7:1
