A typically enlightening sermon on heaven, with Keller providing detailed insights into what heaven is.
"When the Bible speaks of the new heaven and the new earth, it is not speaking of an alternative to this world; it is speaking of the healing and restoration of this world.
This gives Christians a reason to participate in restoring this fallen world. Furthermore, because Christians know that there is a perfect world coming, they don't put all their hope in the current world. Christians can sacrificially serve others because they value the things of the coming world more than the things of this world."
Additional scriptural references made in this sermon are: Revelation 21:1-2; Genesis 3; Romans 8:18.
