Luke 1:48 For he hath regarded the low estate of his handmaiden: For, behold, from henceforth all generations shall call me blessed.
Mary knew that she was blessed. She called herself a handmaiden. A handmaiden was a female slave. It was her duty to be at hand an to obey. She realized that God had greatly blessed her given her this opportunity. She knew that people would call her blessed from this day forth.
She was praising God. It was undeserved. It was God’s grace. It was God doing great things to her.
That is what happened to us as well. We were slaves to sin. We were nobodies. We had no hope. He saved us. He blessed us.
We might not realize how much unless we are willing to recognize where we were when He saved us.
