Mary didn’t know exactly when Jesus would be born, or more importantly, she didn’t know she would be His mom, but she lived her life knowing it could happen at any time.
She didn’t want to miss out on what God planned to do when he sent the Messiah.
Because she took time to know God’s word and understand it, she used her knowledge of God’s word in order to live a life that would be pleasing to God.
Imagine what kind of a life she must have lived in order to be chosen to be Jesus’ mom? Not only in deed, but in her heart!
Her heart matched her lifestyle. It’s possible to live a good life on the outside, and do all the right things, but still not have a relationship with God.
The point here is that because she not only believed God’s word, she lived it.
