I have been replaying Luke 1:48 and Luke 11:27-28 in my mind. Something doesn't make sense here. Luke 1:48 is the part of Mary's song where Mary announces that all successive generations will call her blessed because of her son Jesus. Then, in Luke 11:27-28, when Jesus is a grown man in his ministry, a woman tells him that his mother is blessed for carrying him in the womb and nursing him, which ironically seems to allude to what Mary says earlier, but Jesus replies, "Blessed rather are those who hear the word of God and obey it." Apparently, Jesus is not concerned with his own pedigree, and if that is the case, does this mean that he rejects Mary's happiness? What's going on here?
Jesus' answer emphasizes what is more important. It is more important that a person hear the word of God and obey it than to be chosen by God for some special task. Not everyone will be chosen for a special position, but anyone can choose to obey God.
Jesus puts things regarding (his own) family into perspective: they are not as important as seeking the kingdom of God. When his family shows up, seemingly to talk some sense into him, Jesus tells the crowd:
Regarding familial relationships and the call of God, he says:
Nothing is more important than responding to God's call.
I don't think it's necessary to conclude that Jesus rejects his mother's happiness or her elevated position. He only tells the rest of us: don't wish you were her; instead, obey God.
A different interpretation:
Filled with the Holy Spirit, Elizabeth said to Mary -
The Holy Spirit connects Mary's blessedness with the fact that she believed in God's word. Jesus says the same thing -
It seems to me that according to Jesus, Mary's blessedness doesn't proceed from the fact that she gave him birth, but from her faith in the word of God. If we want to be blessed, we must have faith in God's word and also obey it, just like Mary. Surely one is blessed if one gives birth to God's Son, but one is more blessed if he/she believes in God's word and keeps it.
Mary's blessedness is not from her being but from her belief (cf. Luke 1:45; Luke 1:48).
Do Luke 1:48 and Luke 11:27-28 contradict each other?
The Greek word translated as "rather" is "μενοῦνγε" and it could mean either"no rather" or "nay but yea" or "more than" (source). The following translations reflect these meanings:
In NASB, Jesus is saying that blessing Mary [in consanguinity] is not what brings blessing but rather, being a hearer and doer of the word is what brings blessing.
In NLT, Jesus is saying that what is "more blessed " is not those who bless Mary but those who are scripture hearers and doers (Luke 11:27-28).
Taking these passages with the Scriptures "as a whole", it shows that the reading of NASB is much accurate:
Luke 1:48 does not contradict Luke 11:27.Apparently, Jesus is not concerned with his own pedigree and this does not affect Mary's blessedness which is clearly evinced as coming from her faith not from her flesh:
