Failing to find a vocation in ministry, Van Gogh turned to art as a means to express and communicate his deepest sense of the meaning of life. Cliff Edwards, author of "Van Gogh and God: A Creative Spiritual Quest" wrote: "Vincent's life was a quest for unification, a search for how to integrate the ideas of religion, art, literature, and nature that motivated him."^[1]

Van Gogh came to view painting as a calling, "I feel a certain indebtedness [to the world] and... out of gratitude, want to leave some souvenir in the shape of drawings or pictures -- not made to please a certain taste in art, but to express a sincere feeling."^[2] When Van Gogh left Paris for Arles, he sought an anecdote to the ills of city life and work among laborers in the field "giving his art and life the value he recognized in rural toil."^[3]

In the series of paintings about wheat fields, Van Gogh expresses through symbolism and use of color his deeply felt spiritual beliefs, appreciation of manual laborers and connection to nature.

As a young man Van Gogh pursued what he saw as a religious calling, wanting to minister to working people. In 1876 he was assigned a post in Isleworth, England to teach Bible classes and occasionally preach in the Methodist church.^[4][5]

When he returned to the Netherlands he studied for the ministry and also for lay ministry or missionary work without finishing either field of study. With support from his father, Van Gogh went to Borinage in southern Belgium where he nursed and ministered to coal miners. There he obtained a six-month trial position for a small salary where he preached in an old dance hall and established and taught Bible school. His self-imposed zeal and asceticism cost him the position.^[5]

After a nine-month period of withdrawal from society and family; he rejected the church establishment, yet found his personal vision of spirituality, "The best way to know God is to love many things. Love a friend, a wife, something - whatever you like - (and) you will be on the way to knowing more about Him; this is what I say to myself. But one must love with a lofty and serious intimate sympathy, with strength, with intelligence."^[5] By 1879, he made a shift in the direction of his life and found he could express his "love of God and man" through painting.^[4]

Drawn to Biblical parables, Van Gogh found wheat fields metaphors for humanity's cycles of life, as both celebration of growth and realization of the susceptibility of nature's powerful forces.^[6]

• Of the Biblical symbolism of sowing and reaping Van Gogh taught in his Bible lessons: "One does not expect to get from life what one has already learned it cannot give; rather, one begins to see more clearly that life is a kind of sowing time, and the harvest is not here."^[7

  The Sower, June 1888, Kröller-Müller Museum, Otterlo. Inspired by Jean-François Millet Van Gogh made several paintings after The Sower by Millet
  The image of the sower came to Van Gogh in Biblical teachings from his childhood, such as:

"A sower went out to sow. As he sowed, some seed fell along the path, and the birds came and devoured it. Other seed fell on rocky ground, where it had not much soil, and immediately it sprang up, since it had no depth of soil; and when the sun rose it was scorched, and since it had no root it withered away. Other seed fell among thorns and the thorns grew up and choked it, and it yielded no grain. And other seeds fell into good soil and brought forth grain, growing up and increasing and yielding thirty fold, and sixty fold and a hundredfold.(Mark 4:3-8)^[7]

• Van Gogh used the digger and ploughman as symbols of struggle to reach the kingdom of God. ^[8]

• He was particularly enamored with "the good God sun" and called anyone who didn't believe in the sun infidels. The painting of the haloed sun was a characteristic style seen in many of his paintings, ^[9] representing the divine, in reference to the nimbus in Delacroix's Christ Asleep During the Tempest.^[10]

• Van Gogh found storms important for their restorative nature, symbolizing "the better times of pure air and the rejuvenation of all society." Van Gogh also found storms to reveal the divine. ^[11]

I love fields!
