An illustration of Luke 13:18-19 where Jesus says, 'What is the kingdom of God like? It is like a mustard seed, which a man took and planted in his garden. It grew and became a tree, and the birds perched in its branches.' The artistic medium should be watercolor. The scene can be set in a tranquil garden, with a man tenderly planting a small mustard seed which grows into a large tree. A group of different species of birds perch on the tree's branches, symbolizing the kingdom of God.
