Revelation 21:8

In contrast to the rewards of those who overcome is the punishment of the wicked in the lake burning with fire and brimstone. John now gives a list of some who will be included in that group. The fearful are those who run when the battle is joined. (Hebrews 10:38-39) The unbelieving are those who know the Lord's will but do not do it in preparation for his return. (Luke 12:45-48) Those who are foul and polluted because of association with idolatry and the sins surrounding it would be considered abominable. Murderers willfully take lives of others with no respect for life or law. Whoremongers are fornicators or those who participate in any illicit sexual activity. Sorcerers use drugs and magical arts to control others. Worshippers of anything but the true God would be known as idolaters. Liars can lie by word, through intimation or silence. (Acts 5:1-11)
