What does the Bible say about the promise of a new heavens and a new earth?

In 2 Peter 3:13, we are encouraged by the promise that we, according to His promise, look for new heavens and a new earth, wherein dwelleth righteousness. This promise points to the ultimate hope of believers—a renewed creation that is free from sin and filled with the glory of God. The significance of this promise is profound, as it assures Christians that the present world's suffering and corruption will not persist forever. Instead, God will create a new existence, confirming His faithfulness and commitment to redeem His people and all creation.
