The Quran says that Paradise is the Home of Peace (10:25) This means that there will be peace everywhere in Paradise. Paradise will be a peaceful society. It will be completely peaceful. 
We speak about peace in this world. But where is peace here?
The Quran says about Paradise: "They will not hear therein any vain or sinful talk." (56:25) This means that there will be no nuisance in Paradise. There will be no nuisance because no one will create nuisance in Paradise. The people of Paradise will live with self-restrain. They will not create problems for anyone. This is why Paradise will have no nuisance. This means that people of Paradise will be highly developed persons. They will be mature, wise and live as no-problem persons. They will not create the least problem for anyone. They will not create nuisance for anyone. In this world, if someone makes you angry and you get provoked, you prove that you are undeserving of Paradise. If you suffer loss and decide to take revenge, you prove that you are not deserving of Paradise. If you become negative on facing unpleasant experience, you prove you are not deserving of Paradise. The Quran and Hadith tell us that this world is a testing ground. 
How will this test be?
If everything is smooth and proper here, no loss, no provocation, 
then how will you be tested?
This world has been made by God as a world of problems. In the midst of all these problems, it will be tested whether you have a character of the people of Paradise, or you do not have the character of people of Paradise.
