What does this parable mean?
It means you better get to studying, and stop asking so many questions, but I am joking.
Old wine, the ways of the flesh, sins.
New wine, the ways of the Spirit.
Luk 5:37 And no man putteth new wine into old bottles; else the new wine will burst the bottles, and be spilled, and the bottles shall perish.
New wine cannot go in to old bottles, for a person must be forgiven of their sins, a new vessel, to be able to receive the Holy Spirit.
And those without the new wine, the Holy Spirit, shall perish.
Luk 5:38 But new wine must be put into new bottles; and both are preserved.
New wine goes in to new bottles, and they both are preserved, the Holy Spirit goes in to new vessels when their sins are forgiven.
Without the forgiveness of sins to get rid of the old wine, the new wine, the Holy Spirit, cannot be active in their life for salvation.
Luk 5:39 No man also having drunk old wine straightway desireth new: for he saith, The old is better.
The world will not repent of their sins, and not believe the truth, and does not desire the new wine, for they say the old wine is better, the ways of the world.
