1 Corinthians 15:16-20

16 For if the dead are not raised, not even Christ has been raised. 17 And if Christ has not been raised, your faith is futile and you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished. 19 If in Christ we have hope[a] in this life only, we are of all people most to be pitied.

20 But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep.

Revelation 21:9-11

The New Jerusalem

9 Then came one of the seven angels who had the seven bowls full of the seven last plagues and spoke to me, saying, “Come, I will show you the Bride, the wife of the Lamb.” 10 And he carried me away in the Spirit to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God, 11 having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal.
