Jude 1:3-4 - Jude's Purpose In Writing
3 Beloved, making all diligence to write to you about the common salvation, I had need to write to you exhorting you to earnestly contend for the faith that was once for all delivered to the sanctified. 4 For certain men have sneaked in, those written about formerly for this condemnation, irreverent men, perverting the grace of our God into licentiousness, and denying our only Master God, and our Lord Jesus Christ.
