2 Thessalonians 2:8-10
And then the lawless person [See verse 3] will be revealed, the one whom the Lord Jesus will destroy with the breath of His mouth and bring to an end by the brilliant appearance of His presence [i.e., at His second coming].
1 Timothy 4:1-2
Now the Holy Spirit specifically says that in later times [Note: "Later times" in the New Testament usually refers to the period following the first coming of Christ and the establishment of the church], some people will fall away from the faith [i.e., the true teaching of Christianity]. They will pay attention to deceitful spirits [i.e., lying people] and the teaching of evil spirits.
2 Peter 2:1-3
But just as there were false prophets among the people before, there will also be false teachers among you [Christians]. They will privately teach harmful doctrines that destroy people [spiritually], by even denying [that Jesus is] the Master, [and thereby] destroying themselves quickly.
Revelation 19:20
But the beast was captured, along with the false prophet [See 16:13], who performed [supernatural] signs in his presence. [He had performed these signs] to deceive those who had received the mark of the beast and those who worshiped his statue. [See 13:15-16]. The beast and the false prophet were both thrown alive into the lake of fire that burns with sulphur.
Revelation 21:8
But the place for cowards, and unbelievers, and disgusting people [i.e., because of their terrible sins], and murderers, and sexually immoral people, and sorcerers, and idolaters, and all liars, will be the lake that burns with fire and sulphur. This is the second death."
Revelation 22:15
On the outside [of the city] are the dogs [Note: This probably refers to people who practiced sexual perversions. See Deut. 23:17] and the sorcerers, and the sexually immoral people, and the murderers, and the idolaters and every person who loves and practices falsehood.
