Jude 1:3-4 - Jude's Purpose In Writing
3 Beloved, making all haste to write to you concerning our common salvation, I had need to write to you, exhorting you to agonize for the faith which was once delivered unto the saints. 4 For certain men have crept in, who long ago were written down to this judgment, ungodly, transforming the grace of God into impurity, even denying Jesus Christ, our only Sovereign and Lord.
