Jude 17-19

But dear friends, remember what the apostles of our Lord Jesus Christ foretold. They said to you, "In the last times there will be scoffers who will follow their own ungodly desires." These are the people who divide you, who follow mere natural instincts and do not have the Spirit.

remember what the apostles 
Ephesians 4:11-12  So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers, to equip his people for works of service, so that the body of Christ may be built up ...

of our Lord Jesus Christ foretold 
Hebrews 2:3  ... how shall we escape if we ignore so great a salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him.
2 Peter 3:2  I want you to recall the words spoken in the past by the holy prophets and the command given by our Lord and Savior through your apostles.

They said to you, "In the last times" 
1 Timothy 4:1  The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.
2 Timothy 3:1  But mark this: There will be terrible times in the last days.
2 Peter 3:3  Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires.

there will be scoffers who will follow their own ungodly desires 
Jude 16  These people are grumblers and faultfinders; they follow their own evil desires; they boast about themselves and flatter others for their own advantage.
2 Peter 2:1  But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the Sovereign Lord who bought them--bringing swift destruction on themselves.

These are the people who divide you, who follow mere natural instincts and do not have the Spirit 
1 Corinthians 2:14-16  The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit. The person with the Spirit makes judgments about all things, but such a person is not subject to merely human judgments, for, "Who has known the mind of the Lord so as to instruct him?" (Isaiah 40:13) But we have the mind of Christ.
