"But one thing is needed, and Mary has chosen that good part, which will not be taken away from her."
Mary, a woman after God's own heart, made the choice that indicated her heart's devotion: She knew it was important to cease her busyness, stop all activity, and set aside secondary things in order to focus wholly on the Lord.
Unlike her sister, who was so busy doing things for the Lord that she failed to spend time with Him. Mary put worship at the top of her to-do list.
The word "priority" means "to prefer". We want to choose to prefer God's way in all things.
