Unum Necessarium

Gospel of Luke, 10:38-42:
Now it happened as they went that He entered a certain village; and a certain woman named Martha welcomed Him into her house. And she had a sister called Mary, who also sat at Jesus' feet and heard His word. But Martha was distracted with much serving, and she approached Him and said, "Lord, do You not care that my sister has left me to serve alone? Therefore tell her to help me."
And Jesus answered and said to her, "Martha, Martha, you are worried and troubled about many things. But one thing is needed, and Mary has chosen that good part, which will not be taken away from her."
