Isaiah 45:4
“For the sake of Jacob My servant, And Israel My chosen one, I have also called you by your name; I have given you a title of honor.
Thus when a name is changed or a title given by God, it shows how God sees this person --- or who this person really is---
Abram --> Abraham (father of nations)
Sarai --> Sarah (princess)
Jacob --> Israel (he who wrestles with God)
Simon --> Cephas (Rock)
and then, in a wonderful fashion:
Mary --> Kecharitomene (she who has been filled with grace)
To grasp these truths from Scripture concerning Mary, you have to realize two things: first, there was a need for Jesus the Messiah to be perfect in His human nature and in is earliest human nurture; and second, God announces that He has destined that this perfect human nature and nurture would be given to the Messiah by his mother Mary. Who is Mary in His eyes? Kecharitomene.
We don't grasp the full significance of this Scripture, because our knowledge and wisdom are limited. We don't get the full breadth and depth of things unless we sincerely ask for the Holy Spirit Who teaches the fullness of the truth, as Jesus said.
Here's a good video (11 min) about God's favor to his handmaid Mary, through Scripture:
It's just a brief outline, but it sketches what we know about God's gracious and exceptional gift: Mary was foreshadowed in the OT and foretold to be the sinless Mother of God's perfect Son.
These Scripture types and images in the OT find their fulfillment in the NT in Mary's role in the coming of the Messiah.
>> “first, there was a need for Jesus the Messiah to be perfect in His human nature” <<
.
Yes, that required that his mother be a sinner as she was.
.
>> “We don’t grasp the full significance of this Scripture...” <<
.
The real significance is that Mary, like all humans was full of sin, and needed to be filled with grace to save her soul.
Those people in the bible show how they reacted to GOD - they believed HIM and His favor flowed!! And they accepted 'the assignment' on their life - and each of us has one. The same as today - we are to HEAR and OBEY HIM alone - and how many do? That is the will of The FATHER.
How many would be as faithful as Joseph, for example. He had a dream, believed it, spoke of it and his own family/brothers left him in a pit because 'he thought he was special' and then lived as a slave and thrown in jail and for 13 years kept that one dream alive - because GOD was HIS FINAL authority. He didn't believe anyone but GOD knewGod.
HIS ONE dream was enough for HIM!! You have the WORDS of JESUS for YEARS and still listen to 'man' and are persuaded by 'man'. You would never have been thrown in a pit, etc - and been able to do the things Joseph (and others listed) did. And Joseph would have missed his destiny if he listened to another! And many many do miss it because they don't believe JESUS and ONLY JESUS! Only those that are able to do the Father's will are those we hear and obey ONLY HIM!
If you claim Jesus is your Savior - then how could you possibly listen to anyone else? Why would you? Either you believe JESUS is LORD over all or HE isn't. There is NO a little of this and a little of that. Either His Word is your FINAL authority or it isn't. God's WORD IS the Final authority or you don't believe HIM.
And you get no title for it - being 'one of HIS' and spending LIFE eternally with HIM should be enough. It IS for all those who do belong to HIM and they are called Christians - those who listen to Jesus The Christ ALONE.
