Revelation 21:7-8 (ESV)

15 And another angel came out of the temple, calling with a loud voice to him who sat on the cloud, “Put in your sickle, and reap, for the hour to reap has come, for the harvest of the earth is fully ripe.” 16 So he who sat on the cloud swung his sickle across the earth, and the earth was reaped.

4 Yet you have still a few names in Sardis, people who have not soiled their garments, and they will walk with me in white, for they are worthy. 5 The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels. 6 He who has an ear, let him hear what the Spirit says to the churches.’
