“Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives 12 as you look forward to the day of God and speed its coming.[b] That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. 13 But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.” (II Peter 3:11-13 NIV)
Evil must be destroyed, and so must the physical universe. But those who repent and believe in Jesus for salvation can look forward to a new heaven and a new earth where there is no sin.
