Jude 1:3-4 - Jude's Purpose In Writing
3 Beloved, making all haste to write to you, concerning the common salvation, I thought it necessary to write to you, exhorting you to contend earnestly for the faith formerly delivered to the saints. 4 For certain men have come in privily, who long ago were before written to this very condemnation; ungodly men, perverting the favor of our God to lasciviousness, and denying the only sovereign Lord, even our Lord Jesus Christ.
