John 14:27
Peace I leave with you; My peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be fearful
Philippians 4:6
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 comprehension, will guard your hearts and your minds in Christ Jesus.
