Yet with peace I think that when satan is in the world there is no perfect world.
And about the peace in the world:
1 Thessalonians 5:2 for you know very well that the day of the Lord will come like a thief in the night. 3 While people are saying, ‘Peace and safety’, destruction will come on them suddenly, as labour pains on a pregnant woman, and they will not escape.
For that
John 14:27 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.
Colossians 3:15 Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful.
