Peter tells us that the Lord is not slack concerning His promise. That is not a characteristics too common among people. It seems that many are not too concerned about being true to their word. But God is faithful to His Word every time and in everything.

    After the flood in the time of Noah God made a promise that He would not destroy the world again by water. He did not say He would not destroy the world. In fact, as Peter tells us of the faithfulness of God to His promise he also tells us of the coming end of the world by fire.. The world and all the elements thereof shall be burned up.

    God keeps His promises. As surely as the world will not be flooded again, it will perish. (By the way, we can know the Noah flood was not just a local thing because the end of the world will not be local but universal also).
