In Luke 13 Jesus tells his followers to repent or perish and explains how to reach the Kingdom of God.
The Parable of the Mustard Seed (Luke 13:18)
Jesus used parables to teach big ideas and concepts in ways that the crowds who listened to him would understand.
The parable of the mustard seed explains the Kingdom of God. It started with one seed (Jesus), grew into a large tree (church), that birds perched on using its resources.
Jesus will reference the mustard seed again in Luke 17 when He talks about being strong in faith.
The Narrow Door (Luke 13:22-30)
Jesus talks about entering the Kingdom through the narrow door (or depending on your translation, gate) while He is in Jerusalem. Jesus is headed toward His destiny, the Passion.
On His way to Jerusalem someone asks him how many people will be saved. Jesus answers with a parable about a homeowner throwing a banquet. Guests are supposed to enter through the narrow door, those who do get in to enjoy the banquet. Those who do not are left outside the home knocking at the door, turned away by the host who announces that he does not know them because his guests, whom we knew, would have the directions about how to enter.
Jesus says that He is the way to the Kingdom- the narrow door we use to enter the banquet.
Jesus’ Sorrow for Jerusalem (Luke 13:31-35)
The Pharisees found Jesus and told him to leave Jerusalem because Herod wanted to kill him.
He replied, “Go tell that fox, ‘I will keep on driving out demons and healing people today and tomorrow, and on the third day I will reach my goal.’ In any case, I must press on today and tomorrow and the next day—for surely no prophet can die outside Jerusalem!(Luke 12:32-33)
Enter through the Narrow Gate, welcome the Holy Spirit.
Holy Spirit, You are welcome here
Come flood this place and fill the atmosphere
Your glory, God, is what our hearts long for
To be overcome by Your presence, Lord. -Lyrics from “Holy Spirit” by Francesca Battistelli
