Amen. You said it much better than I did.
And just as God made Mary accepted, so does the righteousness of Jesus Christ make all of us accepted to God, by His grace alone.
Accepted, justified, sanctified, purified- just like Mary was; and not of ourselves, as it was not of herself. Given grace- not an abstract power, but God's Mercy at Christ's expense. Faith in that wonderful God's atoning power allows us to call Him, "Savior" - just like Mary did.
Goodnight my friend.
