From the New Testament:

YIKES!   Romans 1:24 Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. 25 They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator--who is forever praised. Amen.
Don't let this happen! Romans 1:26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.
Ignorance!   Ephesians 4:18-20 18 They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts. 19 Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, with a continual lust for more.
SCARY!   Galatians 5: 19 The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, distensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
Sad!  2 Corinthians 12:21 I am afraid that when I come again my God will humble me before you, and I will be grieved over many who have sinned earlier and have not repented of the impurity, sexual sin and debauchery in which they have indulged.
No heaven?  1 Cor 9 - 11  9 Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
Stamp of approval? Romans 1:28-32  28 Furthermore, since they did not think it worthwhile to retain the knowledge of God, he gave them over to a depraved mind, to do what ought not to be done. 29 They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, 30 slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; 31 they are senseless, faithless, heartless, ruthless. 32 Although they know God's righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them. NOTE:  You mean all I have to do is just approve of those who practice these things and I'll be condemned along with them?  I better speak up against it and not do it myself.
Tricked? Coll 2:8 See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the basic principles of this world rather than on Christ.
Warning is good!  Jude 1:22 Be merciful to those who doubt; 23 snatch others from the fire and save them; to others show mercy, mixed with fear, hating even the clothing stained by corrupted flesh.  "Rescue those being led away to death; hold back those staggering toward slaughter."  Proverbs 24:11
Example? Jude 1:7 In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire.
Godless men? Jude 1:4 They are godless men, who change the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.
Keep your clothes on?  Revelation 16:15  "Behold, I come like a thief!  Blessed is he who stays awake and keeps his clothes with him, so that he may not go naked and be shamefully exposed.
Cover it up!  Rev 3:18  I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see.
Watch your mouth, too.  Ephesians 5:3-8  3 But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people. 4 Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. 5 For of this you can be sure: No immoral, impure or greedy person--such a man is an idolater--has any inheritance in the kingdom of Christ and of God.
So prevalent?  James 1:21 Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you. 


From the Old Testament:

Job said this!  Job 31  1 "I made a covenant with my eyes not to look lustfully at a girl.  2 For what is man's lot from God above, his heritage from the Almighty on high?  3 Is it not ruin for the wicked, disaster for those who do wrong?
Are you too smart?  Isaiah 5: 20, 21 21 Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter. 21 Woe to those who are wise in their own eyes and clever in their own sight.
Don't peek!  Habakkuk 2:15 "Woe to him who gives drink to his neighbors, pouring it from the wineskin till they are drunk, so that he can gaze on their naked bodies.
