What will happen to the universe when God destroys it at the end?

Les sees that as exactly what God will do: when everything is destroyed and the elements melt with fervent heat, God will pull everything back into that original source of light and energy. From there He will create new heavens and a new earth, as Revelation tells us, and so does Peter.
