Jude 1:17-21

But ye, beloved, remember ye the words which have been spoken before by the apostles of our Lord Jesus Christ; that they said to you, In the last time there shall be mockers, walking after their own ungodly lusts. These are they who make separations, sensual, having not the Spirit. But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Spirit, keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
