How do you compare to Mary?
Luke 11:27-28 As Jesus was saying these things, a woman in the crowd called out, "Blessed is the mother who gave you birth and nursed you." 28 He replied, "Blessed rather are those who hear the word of God and obey it." 
What an astonishing statement this is! The woman was right. She was saying the same thing Mary said in her Magnificat, which was surely inspired by God. “All generations will call me blessed.” (Lk.1:48) She was indeed blessed. Oh, how blessed. Anyone who would not regard it as a high honor to have carried the Son of God and brought Him into this world and nursed Him and raised Him and cared for Him in all the ways a mother cares for a child – anyone who would not see that as a high, high honor would be a fool. I would consider it a great honor and great blessing and it would fill me with great joy even if I could have so much as met Him when He walked this earth, and especially if I could have shown some kindness to Him. If I met Jesus when He was a little child, and some bullies were terrorizing Him, if I could have come along as an adult at that moment and run the bullies off to protect Him, and that caused delight in His 8 year old human heart – I would consider that a grand privilege. How much greater the blessing of being His primary caregiver the entire time He was growing up. To witness firsthand what a perfect child is like. The things that so many of us have wondered – when does a perfect child cry or not cry, how does a perfect child handle pain, etc. – Mary didn’t have to wonder. She got to see them firsthand, and treasured them in her heart. Oh, the blessedness of Mary! 
But Jesus' reaction when this was expressed was not to affirm it, but to downplay it in comparison with a much greater blessedness. My first impulse when I wrote the last paragraph was to say that anyone who didn’t regard this as the highest of honors would be a fool. But that’s not correct. It was an immeasurably high honor for Mary, but it was not the highest of honors. Jesus pointed out a much higher honor, a much greater form of blessedness, a much surer avenue to joy – hearing and keeping His Word. 
Christopher Love made some excellent observations about this: 
Again, it is not said, "Blessed also," but "Blessed rather." Christ does not say, "My mother is a blessed woman, and they also are blessed who hear the Word of God and keep it." But Christ comes in with a "rather." It is as if He had said, "I account those men and women more blessed than My own mother, merely for being instrumental in bringing Me into the world." Oh, how should the consideration hereof enflame your hearts, and provoke you to a diligent hearing of God's Word, and a conscientious practicing of what you hear? There is not the like phrase in all the Bible. … If it is so that they who hear and keep the Word of God are more blessed than the Virgin Mary was merely for bringing Christ into the world, should not this then be for a lamentation that men will not seek after blessedness when they may have it upon such easy terms? Had God said, "I will bless you if you remove mountains, if you fulfill My law in every jot and tittle thereof," these indeed would have been impossible works to be done. But God said, "Blessed are you if you hear the Word of God and keep it." …
OBJECTION. But you will say, "If they only are blessed who hear the Word of God and keep it, who practice what they hear, then where is a blessed man to be found? For where is that man alive who can keep, who can live answerably to what he hears? …
ANSWER. … for your comfort know that you are under a covenant of grace, which does not require a perfect, but a sincere obedience to the law of God, which accepts the will for the deed. … a covenant of grace, which accepts what Christ has done and suffered for you (if you are a believer) as if it were done in your own person. … In a word, make conscience to keep what you hear; bewail your inability to fulfill the law of God; do what you can, and mourn that you can do no better; and then God will say, "Though you cannot keep the law completely, yet My Son has kept it for you. I accept His obedience as your obedience, and His righteousness as your righteousness." Oh, what grace and mercy is here! How may this cheer up your hearts in the midst of all discouragements that lie upon you!  – Christopher Love (from the sermon A Description of True Blessedness
 
Dear Lord, please forgive me for how lightly I’ve taken the grand privilege of hearing and keeping Your Word. That I could have access to a blessedness greater than Mary’s! And that I could have it on such easy terms! Thank You, dear Lord! Teach me to prize this blessedness as I ought. Teach me to enjoy it and to greatly delight in a God who would offer such a blessedness to such as I.
