As recorded by Mark in chapter four, Jesus continues teaching in parables that the Kingdom of God is being manifest through His disciples. What was once a mystery and at times seemed hidden is now being brought to light. Jesus instructs His disciples that the light which is shining in their hearts is not to be hidden but to be put on display for all to see. The fruit they see proves the Kingdom of God is upon them. God is working in a special way. Their efforts, big or small, when aligned with the Kingdom vision of Jesus will not be made in vain. Small efforts of faithfulness can give way to great Kingdom expansion.
