Mary in the Heart of every Christian.

From Vatican's Agenzia Fides:

The presence of the Mother of God in our lives is closely connected with the plan for sanctification and transformation which the Father, in Christ, has for each of us. Christ’s words “Behold your mother” (Jn 19, 27) are also the words of the Father consigned with the Holy Spirit to every disciple.
The Blessed Virgin Mother has at heart our conversion which naturally depends on a life of prayer which opens us to charity. As at Cana, Mary intercedes for us as an Advocate of grace.

Mary is only mentioned 19 times in scripture, but every time she is mentioned she points to her Son or to God the Father. From the Annunciation to Pentecost her purpose is to show us how a true disciple accepts God's grace and follows her Son. Her last recorded words in the Gospel of John (2:5):

His mother said to the servers, “Do whatever he tells you.”

shows us the way.
