There is a very well-known parable taught by Jesus in the gospels; The Parable of the Sower. In this teaching we learn about the way in which seeds respond when sown in different soil types. Jesus teaches that the soil types represent our hearts when receiving His Word, and how the word responds depending on the condition of our hearts.
One of the most significant ways that we can sow into the Kingdom of God, is by sowing the Kingdom into the hearts of our children. This does not happen through structured theological teachings and rote memorization of scriptures but through the beautiful collision of Word and personal experience.
