Commentaries:
During Christ's ministry, a woman tries to draw special attention to Jesus' mother, and Christ puts things in the proper perspective for us.
Jesus agrees that, even though his mother was "happy and to be envied," as the Amplified Bible puts it, even more blessed is anyone who hears God's Word and obeys it. He acknowledges that, yes, His mother was a fine lady—but anyone focusing on the personage of Mary was really missing the point. Christ was interested in the attitude and conduct of people, not their veneration of any human being!
We see a similar phenomenon within mainstream Christianity. Protestants tend to twist the gospel into simply a message about the person of Jesus Christ, and they like to gloss over the message that He actually spoke: "Repent [hear and obey], so you can be in alignment with the soon-coming Kingdom of God!" (Matthew 3:2; 4:17; Mark 1:15). They are so in love with the personality that they cannot hear what He says.
