Jude 17-25 (ESV)
A Call to Persevere
17 But you must remember, beloved, the predictions of the apostles of our Lord Jesus Christ. 18 They  said to you, “In the last time there will be scoffers, following their own ungodly passions.” 19 It is these who cause divisions, worldly people, devoid of the Spirit. 20 But you, beloved, building yourselves up in your most holy faith and praying in the Holy Spirit, 21 keep yourselves in the love of God, waiting for the mercy of our Lord Jesus Christ that leads to eternal life. 22 And have mercy on those who doubt; 23 save others by snatching them out of the fire; to others show mercy with fear, hating even the garment  stained by the flesh.
24 Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, 25 to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen.
