As Jesus was saying these things, a woman in the crowd called out, “Blessed is the mother who gave you birth and nursed you.” He replied, “Blessed rather are those who hear the word of God and obey it.”
Jesus is saying two things here; first that He is made by and part of God; God's son and that he is mothered by God and obeys God. But also that it is not the one who brought him to life on earth who is to be blessed but all those who follow God, including Mary. Jesus blesses us when we follow Him, nothing less and nothing more. what a gift.
