Luke 5:39 – No man also having drunk old wine straightway desireth new: for he saith, The old is better.
“old wine” is fermented alcoholic wine that causes drunkenness, fermentation is a type of leaven which represents corruption. The old wine represents “corruptible seed”.
“new wine” is recently squeezed grape juice that is not fermented, the sugar brightens the countenance. New wine represents incorruptible seed of God’s word.
