"'For John came neither eating nor drinking, and they say, "He has a demon." The Son of Man came eating and drinking and they say, "Here is a glutton and a drunkard, a friend of tax collectors and sinners." But wisdom is proved right by her deeds.'" NIV translation
Jesus goes on to explain that, as with children, what the people wanted could change rapidly. John the baptist had practiced fasting which the religious leaders would normally approve of but still they said that he was demon possessed. In the same manner, Jesus ate and drank with the people but was condemned for that.
Jesus goes on to explain that the wisdom of God is right and it is proved by the lasting work of both John and Himself. God had sent each one in their own role and He was right in doing so.
This serves to remind us that God has a role for each and every one of us as it relates to His kingdom work on this earth. Our efforts may look different from each other and may even appear to be opposites but God knows what he is doing in all things. We are not called to fill the ministry shoes of others but to listen and to follow the direct leading of the Lord in our lives and work.
"Then Jesus began to denounce the towns in which most of his miracles had been performed, because they did not repent." NIV translation
Now, we see a definite turn in the earthly ministry of Jesus as He begins to publicly proclaim judgment on those that fail to repent. We always hear of Jesus' love but many do not want to hear about the fact that Jesus will reject them if they choose to reject Him. As we have already seen, the area of Galilee and the religious people rejected the fact that He was the promised Messiah even though they had seen the miraculous works that were prophesied to accompany Him. In response to their choice, He explains that they will answer for it. We are also reminded of the fact that a failure to embrace Him as the Messiah was considered to be the same as outright denial of Him. In both cases, the result will be destruction.
