Today we celebrate the Solemnity of Mary, Mother of God. More importantly, we celebrate God becoming man. Because of Mary's yes to God, God became man and we have Jesus Christ our Lord. Salvation is the result of the cooperation between God and man, and Mary's cooperation made this possible.
God sent his Son to redeem us and to enable us to be adopted as sons. As the second reading tells us: "The proof that you are sons is that God has sent the Spirit of his Son into our hearts: the Spirit that cries, ‘Abba, Father’, and it is this that makes you a son, you are not a slave any more; and if God has made you son, then he has made you heir." Are we aware of our being adopted sons of God? Are we appreciative and humbled that we have been made heirs? Sometimes in life, we may forget who we are and may go astray. However, God is always waiting patiently for us to come back to Him, just as the father waited for the prodigal son to come home.
Let us thus, like Mary, treasure all these things and ponder them in our heart, for God has given a wonderful gift to us, the gift of His Son. As we also celebrate World Day of Peace, let us bring the peace Christ to all and continue to dwell in His presence.
