What does the Bible say about the new heaven and new earth?

In Revelation 21, we are given a glimpse of a new heaven and a new earth, as John records that the first heaven and the first earth were passed away. This concept is important for believers as it offers hope for a future without sin and suffering. The promise of a new creation underscores God's plan for redemption, where He will dwell among His people, wiping away all tears, sorrow, and pain. This new environment is described as perfect, a stark contrast to the fallen world we currently live in, highlighting the consequences of original sin and the longing for restoration among the faithful.
