Jude 1:3-4

3Beloved, when I gave all diligence to write to you concerning the common salvation, it was needful for me to write to you, and exhort you that ye should earnestly contend for the faith which was once delivered to the saints. 4For certain men have crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
