This episode covers the teaching of Jesus about the nature and scope of His Kingdom. Some in the audience were worried if the Kindom was big enough for everyone or was smaller than the world. Interestingly, Jesus' answer is not about its capacity (in other words, don’t worry about that) but about the size of the entrance door. Jesus tries to switch the focus from the quantitative growth of the Kingdom to the spiritual growth of its citizens. Through divine power, the small, humble beginnings will grow to have a gigantic, cosmic impact.
