In the last times there will be scoffers

Jude 1:14-19
These men are grumblers and faultfinders; they follow their own evil desires; they boast about themselves and flatter others for their own advantage.
Jesus 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.
A question from the apocryphal Book of Enoch. Jude takes his illustrations from books he and his readers know and respect, as well as from the scriptures themselves. apocryphal: (of a story or statement) of doubtful authenticity(真實性), although widely circulated as being true.
Why?
Jesus foretold these word for Jesus knows these challenge will come and reveal the evil mind among men.
People like get together when they have same perspective they will be a party.
There are grumblers and faultfinders among church now. 
Be careful to make friend with those evil men. Away from them!
How?
Insist our faith on the truth, which is told by Jesus Christ and the Lord!
