When reading this parable of Jesus, it follows up with the following text:
"And he spake also a parable unto them; No man putteth a piece of a new garment upon an old; if otherwise, then both the new maketh a rent, and the piece that was taken out of the new agreeth not with the old. 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. But new wine must be put into new bottles; and both are preserved. No man also having drunk old wine straightway desireth new: for he saith, The old is better."
I was surprised at what other readers interpretations were of this parable. Some say that it represents pitting the new way against the old, but I think this is only partially true.
What I have discerned from this parable derives from "when the groom is away, they should fast." Jesus had compared the church to his bride, whom he loves and cherishes. He is saying that when He, Jesus, is not with them, they should become even more disciplined and deny themselves many wants and desires so they can be purified and become new, fresh, and ready to receive wisdom of the Lord, even if he isn't present with them. One must prepare themselves for purity by denying earthly needs. Over-indulging, such as over-eating, too much television, bad habits, etc will lead to the inability of hearing the voice of Jesus in its fullest potential. "Do all things in moderation" as they say.
