Mat 11:18 For John came neither eating nor drinking, and they say, He hath a devil.
Mat 11:19 The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.
The Pharisees were proud of the way they kept the laws and ceremonies, but they were selfish, thinking they knew all about what God required. When John came dressed in repentance garments, they accused him of having a devil. They saw no need for personal repentance, for they were proud of their outward observance of the laws. God looks on the hearts and indeed their hearts needed to repent. Their perception of what was of God was not accepting what their eyes saw, so they rejected John and they would reject Jesus.
They did not like the freedom and liberty that they saw in Jesus. So they accused him of being a drunk who associated with sinners. They would use their perception of the law to condemn Jesus. Their evil hearts twisted the laws and misapplied them to condemn Jesus. Jesus broke no laws, but he did not fit their view; too many were giving him praise and they were jealous. Wisdom is justified of her children. The wisdom of the Pharisees was tainted by envy and malice. They brought forth the death of their Messiah. The wisdom of God flowed from Jesus, bringing life and mercy and healing. The children of the fruit of Jesus become the children of God. Through the ages those who repent and receive Jesus by faith, became the children of God. The wisdom of God brought Jesus Christ our savior and millions of children are born again into the kingdom of God.
Are we wise? Wisdom comes from God. The wise come to Jesus and are given his spirit of truth. What kind of fruit do we have? Our children justify our wisdom. Have we spiritual fruit? Or are we making little selfish Pharisees?
