âBut for the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death.â (21:8)John concludes his overview of the new heaven and the new earth with a serious and solemn warning. He delineates those who will be excluded from any participation in the blessings of heavenâall unforgiven and unredeemed sinners. There are similar lists of such sinners in 22:15; Romans 1:28â32; 1 Corinthians 6:9â10; Galatians 5:19â21; and 2 Timothy 3:2â5. . . .
