And she had a sister called Mary, which also sat at Jesus’ feet, and heard His word. – Luke 10:39

But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her. – Luke 10:42

Little child, thou couldst not climb the mountain, but thou canst sit down at Jesus’ feet; thou canst not understand hard doctrine, but thou canst love Him who said, “Suffer the little children to come unto Me, and forbid them not, for of such is the kingdom of heaven.” Unlearned man, thou who hast no time to acquire earthly lore, if the one thing needful were something that belonged only to the learned, alas for thee; but if thou canst not teach, it is not needful that thou shouldst, it is only needful that thou shouldst learn. Take the Incarnate Wisdom to be thy Master and sit as a little child at His feet to learn with all thine heart. That is all He asks of thee. Men will have it that they must do something to be saved. They must fret and worry like Martha, but after all, the right way is to end your doing and fretting by sitting down content with Jesus’ doing, satisfied with His righteousness and with the merit of His precious blood. The one thing needful is very easy, except to proud hearts, which cannot brook to accept everything gratis, and to be beholden to sovereign mercy. To the poor in spirit, it is not only simple but sweet to sit at Jesus’ feet. I would be nothing but what He makes me, I would have nothing but what He gives me, I would ask nothing but what He promises me, I would trust in nothing but what He has done for me, and I would desire nothing but what He has prepared for me. To sit at Jesus’ feet in humble submission and quiet rest, He the master and I the little child, I the vessel waiting to be filled, and He my fulness, I the mown grass, and He the falling dew, I the rain drop, and He the sun that makes me glisten in life with diamond brilliance, and then exhales me in death to be absorbed in Him; this is all in all to me. ~ C.H. Spurgeon
