And she had a sister called Mary, which also sat at Jesus’ feet, and heard His word. But Martha was cumbered about much serving, and came to Him, and said, Lord, dost Thou not care that my sister hath left me to serve alone? bid her therefore that she help me. And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things: But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her.- Luke 10:39-42

Sitting at the feet of Jesus signifies love. She would not have been sitting there at ease and happy in mind, if she had not loved Him. There was a charm in the very tone of His words to her. She knew how He had loved her, and, therefore, each syllable was music to her soul. She looked up again and again, I doubt not, into that dear face, and often caught the meaning of the words more readily as she read His countenance, marked His eyes ofttimes suffused with tears, and ever bright with holy sympathy. Her love to His person made her a willing learner, and we must be the same. We must not learn of Christ like unwilling truant boys, who go to school and must needs have learning flogged into them; we must be eager to learn; we must open our mouth wide that He may fill it, like the thirsty earth when it needs the shower, our soul must break for the longing it hath towards His commandments at all times. We must rejoice in His statutes more than gold, yea, than much fine gold. When we are moved by this spirit, we have found the one thing needful.

Martha is very busy; she is rather quick tempered also, and so she speaks to the Saviour somewhat shortly; and the Master says, “Martha, Martha,”-very tenderly, kindly, gently, with only the slightest tinge of rebuke in His tone-“Martha, Martha, thou art careful and troubled about many things-but…” That wise and warning but may be very useful to many here. You are engaged to-day in business; very diligent you are in it. You throw your whole energy into your trading, as you must if you would succeed. You rise up wearily, and you sit up late. Shall I say a word that should discourage your industry? I will not; but, but is there nothing else? -is this life all? Is making money everything? Is wealth worth gaining merely for the sake of having it said, “He died worth fifty thousand pounds?” Is it so? ~ C.H. Spurgeon
