"Now as they went on their way, Jesus entered a village. And a woman named Martha welcomed him into her house. And she had a sister called Mary, who sat at the Lord's feet and listened to his teaching. But Martha was distracted with much serving. And she went up to him and said, 'Lord, do you not care that my sister has left me to serve alone? Tell her then to help me.' But the Lord answered her, 'Martha, Martha, you are anxious and troubled about many things, but one thing is necessary. Mary has chosen the good portion, which will not be taken away from her.' " (Luke 10:38-42)
Despite the above contrast between these sisters of Bethany, other passages show that they had something in common: they were faithful followers and servants of Jesus Christ. It appears that their home was a place Jesus stayed fairly often (Bethany is only about two miles from Jerusalem). Based on the language from the Lazarus dying-and-rising passage, we see that they knew Jesus well, trusted in him, and loved him:
"Martha said to Jesus, 'Lord, if you had been here, my brother would not have died. But even now I know that whatever you ask from God, God will give you.' Jesus said to her, 'Your brother will rise again.' Martha said to him, 'I know that he will rise again in the resurrection on the last day.' Jesus said to her, 'I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live, and everyone who lives and believes in me shall never die. Do you believe this?' She said to him, 'Yes, Lord; I believe that you are the Christ, the Son of God, who is coming into the world.' " (John 11:21-27)
"Now when Mary came to where Jesus was and saw him, she fell at his feet, saying to him, 'Lord, if you had been here, my brother would not have died.' When Jesus saw her weeping, and the Jews who had come with her also weeping, he was deeply moved in his spirit and greatly troubled. And he said, 'Where have you laid him?' They said to him, 'Lord, come and see.' Jesus wept. So the Jews said, 'See how he loved him!' But some of them said, 'Could not he who opened the eyes of the blind man also have kept this man from dying?' " (John 11:32-37)
"Then Jesus, deeply moved again, came to the tomb. It was a cave, and a stone lay against it. Jesus said, 'Take away the stone.' Martha, the sister of the dead man, said to him, 'Lord, by this time there will be an odor, for he has been dead four days.' Jesus said to her, 'Did I not tell you that if you believed you would see the glory of God?' So they took away the stone. And Jesus lifted up his eyes and said, 'Father, I thank you that you have heard me. I knew that you always hear me, but I said this on account of the people standing around, that they may believe that you sent me.' When he had said these things, he cried out with a loud voice, 'Lazarus, come out.' The man who had died came out, his hands and feet bound with linen strips, and his face wrapped with a cloth. Jesus said to them, 'Unbind him, and let him go.' " (John 11:38-44)
Later in the book of John we again see the sisters' devotion to Christ:
"Six days before the Passover, Jesus therefore came to Bethany, where Lazarus was, whom Jesus had raised from the dead. So they gave a dinner for him there. Martha served, and Lazarus was one of those reclining with him at table. Mary therefore took a pound of expensive ointment made from pure nard, and anointed the feet of Jesus and wiped his feet with her hair. The house was filled with the fragrance of the perfume. But Judas Iscariot, one of his disciples (he who was about to betray him), said, 'Why was this ointment not sold for three hundred denarii and given to the poor?' He said this, not because he cared about the poor, but because he was a thief, and having charge of the moneybag he used to help himself to what was put into it. Jesus said, 'Leave her alone, so that she may keep it for the day of my burial. For the poor you always have with you, but you do not always have me.' " (John 12:1-8)
Mary and Martha were certainly two separate people. However, we make a mistake if our focus is what makes them different. Better is to remember what they have in common. Like Mary, Anna, and Mary Magdelene, these two sisters showed themselves to be faithful servants of Christ.
