Jesus was asked about the lives of those who suffered and died at the hands of Pilate, and He in turn asked them if they supposed those people were worse sinners than others, because all that mattered was that they repented or they would likewise perish. The same for the people who were killed when a tower fell on them.
Unless you repent you will all likewise perish.
He spoke a parable of a fig tree and, the owner seeing there was no fruit on it wanted to cut it down, but the keeper told him to wait because he will fertilize it and see if it bears fruit. But if not, then he will cut it down.
Next, Jesus was in the synagogue on the Sabbath and a woman with an infirmity of eighteen years, unable to stand upright, was there; and Jesus healed her. She was made straight and glorified God. But the religious rulers, reminded Him of the six days of work and one day of rest, rebuking Him for working on the day of rest. Jesus called them hypocrites and asked which one of them does not lead his ox or donkey to water on the Sabbath. Therefore, He said the woman should be loosed from the bond on the Sabbath. And the leaders were put to shame, but the people rejoiced.
Jesus asked what the kingdom of God was like, and He said it was like a mustard seed that is planted in a garden that grows into a tree where the birds of the air may rest. Or the kingdom is like leaven, which a woman hid in meal until it was all leavened.
Jesus went through the villages towards Jerusalem, teaching, when one asked HIm if there were few who were saved. He replied
Strive to enter through the narrow gate, for many...will seek to enter and will not be able...The Master [will] shut the door and you [will] stand outside and knock...saying, 'Lord, Lord, open for us,' and He will...say..., 'I do not know you...' then you will...say, 'We ate and drank in Your presence, and You taught in our streets.' But He will say, 'Depart from Me, all you workers of iniquity.' There will be weeping and gnashing of teeth when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. They will come from the east and the west, from the north and the south, and sit down in the kingdom of God.
Then Pharisees told Jesus to depart from there because Herod wanted to kill Him. But Jesus rebuked Herod and said on the third day He will be perfected. Then He cried out for Jerusalem saying,
How often I wanted to gather your children together, as a hen gathers her brood under her wings, but you were not willing!
COMMENTARY
The parable of the fig tree, again, represents Israel. When Jesus came, He found Israel not walking in the light, though they were promised blessing if they obeyed God. He would have cut her off, but the keeper of the vineyard said he would fertilize and wait to see if fruit will come, representative of God's patience with Israel. However, Israel has rejected Christ, and they were scattered abroad. Today, those who live in Israel do not live in peace, and there will not be peace in Israel until Jesus returns.
The parable of the mustard seed serves to demonstrate Christendom. The larger it grows the more it loses its true character. The birds symbolize Satan who is always active in influencing the Church. Furthermore, leaven represents evil (hypocrisy). You can see that a little hypocrisy will infect the truth. Some believe leaven to symbolize the gospel in this parable, and that spreading it will convert and save the whole world. But there will be no peace and no kingdom on earth until Jesus returns to establish His kingdom Himself. The Church cannot bring in His kingdom.
When someone asked if few would be saved, Jesus basically told him that the cost of following Him is great. In the OT, we see the multitudes following Christ and glorifying Him and praising Him, but by the time of His crucifiction, it seemed the multitude turned on Him. That is how finicky people are. But in this moment, Jesus told the man to make sure you are saved; don't just assume because you are a Jew that you will go to heaven. Others who are not sons of Abraham, Isaac, and Jacob will be admitted, while you will be standing outside the door, unable to get in.
