Jude (Judah) 1:3-4

Dearly loved friend, I was fully intending to write to you about our amazing salvation we all participate in, but felt the need instead to challenge you to vigorously defend and contend for the beliefs that we cherish. For God, through the apostles, has once for all entrusted these truths to his holy believers. There have been some who have sneaked in among you unnoticed. They are depraved people whose judgment was prophesied in Scripture a long time ago. They have perverted the message of God’s grace into a license to commit immorality and turn against our only absolute Master, our Lord Jesus Christ.
