This artwork describes the new Jerusalem mentioned in the book of Revelation. The river was flowing from the throne of God and on each side of the river stood the tree of life yielding twelve different fruits every month. The city walls were decorated with twelve precious stones and with twelve gates remembering the sons of Jacob.
The world is about to be flooded and there are still obstacles between the snails and the Ark. The sea between the Ark and the snails represents the obstacles the snails have to overcome in order to be safe from the flood. I chose to illustrate this because the Ark, which represents God, provides a sense of hope that motivates everyone – that no matter who you are, to face all your challenges and not give up.
