In the Bible, wheat is a sign of charity and love. The harvesting of wheat is a sign of advanced love and charity, and the field the wheat grows in is representative of the church.
Wheat is also seen as a symbol for those who believe in Christ. Wheat is compared to tares or weeds in the Bible. The weeds or tares are symbolic of unbelievers. In early Christian paintings, a basket of wheat is a sign of self-sacrifice. A man or woman harvesting wheat in a painting is a sign of fertility and productivity, and grains represent the life cycle.
