2 Martha and Mary were two sisters, true kinswomen both, not only in blood, but in religion also; both clave to the Lord, both with one heart served the Lord when He was present in the flesh. Martha received Him, as strangers are usually received. Yet it was the handmaid received her Lord, the sick her Saviour, the creature her Creator. And she received Him to be fed in the body, herself to be fed in spirit. For the Lord was pleased to “take on Him the form of a servant,” and “having taken the form of a servant” in it to be fed by servants, by reason of His condescension, not His condition.
For this truly was condescension, to allow Himself to be fed by others. He had a body, wherein He might hunger indeed and thirst; but do ye not know that when He hungered in the wilderness Angels ministered to Him? So then, in that He was pleased to be fed, He showed favour to them that fed Him. And what marvel is this, seeing He showed this same favour to the widow as touching the Holy Elias, whom He had before fed by the ministry of a raven? Did He fail in His power of feeding him, when He sent him to the widow?
By no means. He did not fail in His power of feeding him, when He sent him to the widow; but He designed to bless the religious widow, by means of her pious office paid to His servant. Thus then was the Lord received as a guest, “who came unto His own, and His own received Him not: but as many as received Him, to them gave He power to become the sons of God:” adopting servants, and making them brethren; redeeming captives, and making them co-heirs. Yet let none of you, as perhaps may be the case, say, “O blessed they who obtained the grace to receive Christ into their own house!”
Do not grieve, do not murmur, that you were born in times when you see the Lord no more in the flesh; He has not taken this blessedness from you. “Forasmuch,” says He, “as you have done it unto the least of Mine, you have done unto Me.”
