The idea of art and God is not uncommon. There are countless paintings of religious works, however to see Gods Hand in a collection of works is rather moving. Vincent Van Gogh's works gives me a sense that his brush strokes and coloring were divinely inspired.
Sure, Starry Starry Night is perhaps Van Goghs most famous work, but The Sunflowers were quite touching. The sunflower always turns to the light of day. Art has a dramatic impact of how one perceives the object in terms of a social statement. It is amazing how people are directed by The Holy Spirit;see God.
In closing, God and Art are one when it comes to comprehending Van Gogh's works. The life of Vincent was one of utter poverty. Now his works are highly valuable. He tried conventional religion but to no avail. Yet art and nature gave him a sense of contentedness that one who suffers much can find in God through art in this particular case.
