NOTES for Luk 8:1-21
Jesus' parables are something halfway between amusing stories from everyday life and riddles: in them He explains the inexpressible, the Message of His Kingdom, in simple human language. Many of them begin just this way: "The Kingdom of God is like someone who..." - and then He sketches a situation familiar to His listeners, revealing to them the essence of His Gospel.
So, the most famous parable is about how the Word of God, like a seed, must fall into fertile soil in order to bear fruit and not be lost in vain. The evangelist wonderfully completes the parable by giving, immediately after it, the account of Jesus' family, where He speaks to the disciples a new riddle that expresses the same Message in other words: "Whoever hears the Word and does it has entered My family".
The listeners only have to compare these parable-riddles to understand what the Kingdom consists in that their Teacher brought to earth. Through his book, the evangelist offers this task not just to the small circle of disciples, but to all readers of the Gospel.
