Matthew 6 - If Thine Eye Be Single, Thy Whole Body Shall be Full of Light

A major theme in this chapter is motives. We should not serve, pray, fast, to be seen of men, but in these devotions we should have our eye on our Father's will. We should trust him to care for us, rather than worrying excessively about our material needs, and seek first to do His will and lay up treasure in heaven. Then our eye will be single, we will be full of light (wisdom and guidance and assistance from the Holy Ghost) and all things will be added to us.
