Jude 1:3-4 - Jude's Purpose In Writing
3 Beloved, using all diligence to write to you of the common salvation, I thought it necessary to write to you, and exhort you to contend earnestly for the faith once delivered to the saints. 4 For some men have stealthily entered in, who were long ago appointed to this condemnation; ungodly men, who pervert the grace of our God, and use it for lascivious purposes, and deny our only Sovereign and Lord, Jesus Christ.
