Luke’s account of Jesus’ early Galilean ministry established Jesus as a uniquely powerful and controversial figure. Jesus placed a premium on mercy, not the traditions of the Pharisees. Something new had arrived and the traditional way of thinking about matters like forgiveness of sin, fasting, and observance of the Sabbath would have to be reconsidered. Jesus’ ministry in Luke 5-6 offered a portrait of His supremacy in Israel’s religion.
(1) In Luke 5:12-26, Jesus demonstrated that He had the power to forgive sin, fulfilling the standards of the Mosaic law. When Jesus cleansed the leper (Matt 8:2-4//Mark 1:40-44//Luke 5:12-14), He warned the man not to make the matter known widely, “But go and show yourself to the priest, and offer what Moses prescribed for your cleansing as a testimony to them” (Luke 5:14). Moses’ instructions in Leviticus 13-14 detailed how priests were to identify and treat skin diseases. The purification protocol Moses established was based on the fact that it took a period of time for skin diseases to run their course. Only after the skin showed no sign of disease could a person return to a state of cleanliness and normal societal relations in Israel. But Jesus cleansed this leper in an instant, simply by His word. Jesus indirectly testified of His messianic status by sending the cleansed man to the priests to tell them what Jesus had done. Luke went on to note that Jesus healed a man who was carried to him on a stretcher and let down through the roof of the home where Jesus was teaching (Matt 9:2-8//Mark 2:3-12//Luke 5:18-26). Luke arranged these healing episodes to emphasize Jesus’ messianic status in accord with Jesus’ proclamation that the Spirit of the Lord was upon Him to set the captives free (Luke 4:18-19). Jesus—in the hearing of the Pharisees and teachers of the law—told the paralyzed man, “So you may know that the Son of Man has authority on earth to forgive sins…I tell you: get up, pick up your stretcher, and go home” (Luke 5:24).
(2) In Luke 5:33-39, Jesus taught that the new covenant required new structures of spirituality. While the Old Testament law required fasting only on the Day of Atonement (Lev 23:26-32), the practice became synonymous with mourning over Israel’s subjection to her enemies (1 Chron 10:12; Zechariah 7-8). The Pharisees traditionally fasted twice per week (Luke 18:12). In the Judaism of Jesus’ day, fasting was looked upon as a special demonstration of one’s piety and concern for the nation of Israel. Some questioned Jesus about why His disciples did not fast like John’s disciples or the Jewish leadership (Matt 9:14-17//Mark 2:18-22//Luke 5:33-39). Jesus answered by saying that the new message of God’s kingdom required a new outlook on spiritual habits like fasting.
(3) In Luke 6:1-5, Jesus claimed to be Lord of the Sabbath. After God created the earth in six days, He rested on the Sabbath (Gen 2:1-2). In Moses’ list of the Ten Commandments in Exodus 20, he stated that God’s Sabbath rest was the reason for Israel to rest on the Sabbath day (Exod 20:8-11). After the destruction of the Second Temple, and even as far back as the days immediately preceding the Babylonian captivity (Jer 17:19-27; Ezekiel 20), Israel and Judah thought the Sabbath second to none in their religion. The Sabbath separated them from all other peoples—showing their special place in God’s plan (Deut 4:1-8). When the Pharisees noticed that Jesus permitted His disciples to pick grain and eat it on the Sabbath, they were out of sorts (Matt 12:1-8//Mark 2:23-28//Luke 6:1-5). Jesus cited David’s unlawful consumption of the showbread when he was on the run from Saul as precedent that His disciples could pick and eat grain. Jesus’ freedom from traditional Sabbath-keeping was an offense to the Pharisees and an affront to any who understood that faithfulness to the rules of the seventh day was the fulcrum of national independence. A new day had dawned.

Luke 7-8
At the outset of his Gospel, Luke told Theophilus that after investigating the matters thoroughly, he set out to write an orderly account of the things that Jesus said and did (Luke 1:1-4). In Luke 7-8, Luke recorded some of Jesus’ messianic miracles and how observers responded to Jesus. When Jesus taught, He presented Himself as the focal point of God’s revelation in the Old Testament. Jesus’ ministry had shared points of contact with the prophets of Israel but ushered in an era that was qualitatively superior. Jesus read Scripture as a storyline that reached its apex in Himself.
(1) In Luke 7:27, Jesus affirmed John the Baptist’s role as His forerunner by quoting Mal 3:1. During the early stages of Jesus’ Galilean ministry, some believed upon Jesus, but others rejected Him. Over time, even John the Baptist began to re-evaluate his cousin. John had baptized Jesus but was soon jailed for preaching against Herod the tetrarch (Matt 14:3-4//Mark 6:17-18//Luke 3:19-20). While Jesus was ministering throughout Galilee, proclaiming the good news and healing many—acts that confirmed His messianic claims—John was left in prison (Matt 11:2-19//Luke 7:18-30). John thought that Messiah would not only preach and heal, but also exercise God’s wrath upon Israel’s enemies in accord with Isa 35:4, “Say to the faint-hearted: ‘Be strong; do not fear! Here is your God; vengeance is coming. God’s retribution is coming; He will save you.’” John thus sent his disciples to inquire of Jesus if Jesus was in fact the Messiah. The Lord answered with deductive reasoning, affirming that John was in fact the messenger who had been sent according to Mal 3:1: “Look, I am sending My messenger ahead of You; he will prepare Your way before You” (Luke 7:27). Since John was the messenger of the Lord, the Lord had indeed arrived. While Jesus emphasized John’s greatness, He also pointed out that an entirely new day had dawned in His coming, saying, “The least in the kingdom of God is greater than he” (Luke 7:28).
(2) In Luke 8:10, Jesus employed the words of the prophet Isaiah to explain His use of parables. As Jesus’ popularity grew, prompted primarily by the miraculous signs He performed, Jesus began to teach in parables. Learning from a parable required ears that had been enabled to discern the thrust of the figure. Jesus used the Parable of the Sower (Matt 13:3-9//Mark 4:3-9//Luke 8:4-8), to communicate the reality that only the good soil responds appropriately to the scattered word. Thus, at the end of the day, the quality of the soil is revealed by the crop it produces. When the disciples were puzzled about the meaning of the Parable of the Sower and asked Jesus for an interpretation, Jesus cited Isa 6:9, saying, “The secrets of the kingdom of God have been given for you to know, but to the rest it is in parables, so that: ‘Looking they may not see, and hearing they may not understand’” (Luke 8:10b). Jesus quoted from the section of Isaiah that records the prophet’s call experience. Isaiah was sent to preach in Judah during the Assyrian advance—a time when the hearts of the people were not receptive to God’s messenger. Jesus’ parables served a dual purpose, revealing the truth of His kingdom to those who had been made perceptive while also hiding God’s word from the hardened.
