There is the peace of the world.

There is the peace of Christ and of God.
“I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world.”
John 16:33

And we know that in all things God works for the good of those who love him, who have been called according to his purpose.
Romans 8:28

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. Philippians 4:6-7

There is the source of peace.

But now in Christ Jesus you who once were far away have been brought near by the blood of Christ. For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility,
Ephesians 2:13-14

and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
Once you were alienated from God and were enemies in your minds because of your evil behavior.
Colossians 1:20-21
