Good luck — if you wish to find peace in the world.
True peace can be found in God.
Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. — John 14:24.
And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. — Philippians 4:7
You will keep in perfect peace those whose minds are steadfast, because they trust in you. — Isaiah 26:3
