41But the Lord answered her, “Martha, Martha, you are worried and distracted by many things; there is need of only one thing. Mary has chosen the better part, which will not be taken away from her.”
Jesus is being playful. Martha is preparing a proper banquet for Jesus. There will be many dishes. “But,” says Jesus, “there is need for only one.”
The double entendre lies in the interplay between the declaration that they do not need a banquet but a single dish, and the scriptural text “Man does not live by bread alone, but by every word that proceeds from the mouth of God.”
Only one thing is needful: the voice of God.
Martha is not being rebuked; she is being teased towards the kingdom. There is a twinkle in Jesus’ eye. Peace does not come to earth because the banquet is done well; it comes in the hearing of God’s Word.
