2 Peter 3:6-7

6Also, God used water to destroy that same world long ago. He spoke his word and he covered the land with water.

7But God has also spoken his word to say what will happen to the world in a future time. The sky and the earth that we see now will continue for a time. But God is keeping them until the day when he will destroy them with fire. On that day he will judge all people. He will destroy the people who have turned away from him.
