I previously wrote,
‘God gave Himself to us by giving Himself to Mary. We are saved through God giving Himself to Mary in Jesus Christ, and through Mary’s “yes”, her giving herself up to God in Jesus Christ. God gave Himself through Mary, and we must receive God, be given up to God, through Mary’s “yes”.’

Mary is the one who accepts Jesus, into her soul, into her womb, and into the universe itself, and it is through her accepting Jesus that we accept Him. She is the one who surrenders her entire life and soul to Jesus, and it is by her surrender that He has taken possession of the world. She is the one who loves Jesus perfectly, giving Him everything and withholding nothing, and it is by her gift that we have been given to Him. She is truly Janua Coeli, the gate of heaven. The salvation of the world was achieved on the cross, but it was received, in all its fulness, in the heart and in the womb of the Blessed Virgin Mary.
Why do we love Mary? Because she is the one who loves Jesus Christ our Lord like no other. She is the mother of God. Her love for Him contains within itself all of the love, in all of creation, for all of time. It is all summed up and perfected in her humble fiat, “let it be done unto me according to your word”, the words that express her entire life. She is the one who gives Him everything.
So when we love Mary, we are loving the one who loves God. And in loving her, we become one with her, and are joined to her, so that she loves God in us, and we love God in her.
And when we love Jesus, we wish to be one with Him, we wish to welcome Him completely into our lives and our hearts, we wish to surrender ourselves perfectly to Him. That is, we wish to be one with the Blessed Virgin Mary.
In short: to love Mary is to love Jesus, and to love Jesus is to love Mary.

God bless you :)
P.S. I was inspired to write this after reading a chapter of ‘Let Yourself Be Led By The Immaculate’ by St Maximilian Kolbe. This is one of the very best books I’ve ever read, and I strongly recommend it, even if you didn’t like what I’ve written here. You can find it on Amazon kindle here
