No doubt Martha was an active sort of person. On one occasion (see Luke 10:38-42) she prepares the meal for Jesus and possibly his fellow guests and forthrightly states the obvious: All hands should pitch in to help with the dinner.
Yet, as Father John McKenzie points out, she need not be rated as an unrecollected activist. The evangelist is emphasizing what our Lord said on several occasions about the primacy of the spiritual: ...[D]o not worry about your life, what you will eat [or drink], or about your body, what you will wear….But seek first the kingdom [of God] and his righteousness (Matthew 6:25b, 33a); One does not live by bread alone (Luke 4:4b); Blessed are they who hunger and thirst for righteousness… (Matthew 5:6a).
Marthas great glory is her simple and strong statement of faith in Jesus after her brothers death. Jesus told her, I am the resurrection and the life; whoever believes in me, even if he dies, will live, and everyone who lives and believes in me will never die. Do you believe this? She said to him, Yes, Lord. I have come to believe that you are the Messiah, the Son of God, the one who is coming into the world (John 11:25-27).
