Jude told the recipients…and us…that creepers had crept in.
For certain persons have crept in unnoticed,
those who were long beforehand marked out for this condemnation,
ungodly persons who turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ.
He tells us that they crept in unnoticed.
He tells us that they are marked for condemnation…from long ago.
He tells us they are ungodfly.
He tells us they turn the grace of god into licentiousness.
He tells us they deny Jesus Christ, our only Master and Lord.
Jude continues by reminding them of things from the Scripture, the Old Testament from their perspective.
He does so by recounting events from their past.
Events that will give insight to the creepers.
Events that will reveal what God did and will do.
Now I desire to remind you,
though you know all things once for all,
that the Lord,
after saving a people out of the land of Egypt,
subsequently destroyed those who did not believe.
This verse is a concise, succinct explanation of God delivering His people from Israel.
He delivered them.
He saved them.
Yet some did not believe.
He destroyed those who did not believe.
(What did they not believe? That God could/would deliver the land promised to them.)
The Lord will deal with unbelievers.
The Lord will deal with creepers.
