God is love right? He is. Hell doesn’t exist, right?
Jude gets into the subject matter by reminding us that God does punish.
“Though you already know all this, I want to remind you that the Lord at one time delivered his people out of Egypt, but later destroyed those who did not believe.” (Jude v 5)
The Lord delivered and He destroyed.
The Lord saves them through the Exodus escaping via the Red Sea yet nearly all of that generation died in the wilderness. Leaving doesn’t mean you arrive.
Every time grace is abused the Law kicks in.
You can experience many blessings from God and not believe in Him and so even the blessed can be punished.
You can start the race but never complete it.
Why?
Somewhere along life’s path you can begin to disbelieve what you had been taught.
Jude warns us that God does punish. He is bigger than the level He is reduced to.
