This artwork by J. Vermeer shows Jesus speaking to Martha while He points to Mary (both ladies were sisters and personal friends of Jesus). Martha is a representation of work, while Mary (who sits listening to Christ) is a representation of contemplation.
The Scripture quote that most likely inspired this painting: "And the Lord answering, said to her: Martha, Martha, thou art careful, and art troubled about many things: But one thing is necessary. Mary hath chosen the best part, which shall not be taken away from her." Luke 10:41-42
