“Jesus called them over and responded with an illustration.” Mark 3:23
When Jesus described the kingdom of God, he used pictures (or parables). This teaching method is more memorable as it engages people’s hearts and minds. It encourages visualisation, and invites people to think. There will always be those who dismiss the illustration and not consider the implications for their own lives. Even in this Jesus had a purpose. Their lack of understanding meant that they hadn’t rejected the plain truth of his teaching. Perhaps in time, their hearts would soften and they would become open to receiving the truth.
