“And the disciples of John and of the Pharisees used to fast: and they come and say unto Him, ‘Why do the disciples of John and of the Pharisees fast, but Thy disciples fast not?’ And Jesus said unto them, ‘Can the children of the bridechamber fast, while the bridegroom is with them? As long as they have the bridegroom with them, they cannot fast. But the days will come, when the bridegroom shall be taken away from them, and then shall they fast in those days.
No man also seweth a piece of new cloth on an old garment: else the new piece that filled it up taketh away from the old, and the rent is made worse. And no man putteth new wine into old bottles: else the new wine doth burst the bottles, and the wine is spilled, and the bottles will be marred: but new wine must be put into new bottles.’” Mark 2:18-22 (KJB)
The religious leaders of Jerusalem, of Israel, had made traditions laws; and those traditions were in many cases loopholes around the law of Moses. Of course the Pharisees held the law of Moses in high esteem, but then violated it; and that is what Jesus is confronting.
The question was asked about fasting. From the previous verses we see that it was the scribes and Pharisees who were asking Jesus this question. They needed the confrontation. O, if only they would have heard.
There are two New things which Jesus mentions; the first is a “New cloth”. The old garment was the old religion of the Hebrews which had been tainted by their traditions which provided loopholes; which was mostly for those in the know about the loopholes which would have been the priests and the scribes and Pharisees. Jesus confronted their sin. You cannot sew a new piece of cloth onto a old piece of clothing with a good outcome. When you wash the garment the new piece will shrink, and tear the old garment, because the old does not shrink. Jesus brought in, brought us the new way of faith and life, fulfilling the law to the max.
The second New thing is “New wine”. Old wine skins have reached their max with the fermentation process, so new wine skins would be needed for new wine. The Spirit of God (the Holy Spirit) is given to all who are born again in Christ Jesus and His finished work on Calvary. The New wine is a picture of that work of the Spirit of God making us new in Him. He is not available for those who refuse to repent of their sins, and refuse to trust in Jesus Christ as their Lord and Savior.
Like the New wine needs in a new wine skin, so too does the Spirit of God work in a new heart given to Christ.
