The Bible says about sexual immorality among Christians

Is your church telling you what the Bible says is God's treatment of sexual immorality? 

This is what the New Testament says happens to Christians:

(1) God's vengeance (1 Cor. 10:1-11, 1 Thess. 4:6, Heb. 13:4)
(2) Huge affliction (Rev. 2:22)
(3) Destruction of the flesh, to save the spirit (1 Cor. 5:5)
(4) Eternal torment in Hell for those do not repent (1 Cor. 6:9, Gal. 5:19-21, Eph. 5:5, Rev. 21:8, Rev. 22:15)
