Jude 1:18-19

18They said to you, ‘In the last days of this world, some people will laugh at God's message. They will say that it is silly to obey God. Instead, they will do the bad things that they want to do. Those things do not please God.’

19It is people like this who cause you to argue with one another, so that you belong to separate groups. Their thoughts belong to this world. They do not have God's Spirit in them.
