This is such a beautiful prayer!
St. John Paul II visited Mexico the first year of his pontificate in 1979. He visited the Shrine of Our Lady of Guadalupe and recited the prayer below.
Prayer to Our Lady of Guadalupe by St. John Paul II
O Virgin of Guadalupe, Mother of the Americas,
grant to our homes the grace of loving and respecting life in its beginnings,
with the same love with which you conceived in your womb the life of the Son of God.
Blessed Virgin Mary, Mother of Fair love,
protect our families so that they may always be united
and bless the upbringing of our children.
Our hope, look upon us with pity,
teach us to go continually to Jesus,
and if we fall, help us to rise again
and return to him through the confession of our faults and our sins
in the sacrament of penance, which gives peace to the soul.
We beg you to grant us a great love of all the holy sacraments,
which are, as it were, the signs that your Son left us on earth.
Thus, Most Holy Mother,
with the peace of God in our consciences,
with our hearts free from evil and hatred,
we will be able to bring to all others true joy and true peace,
which come to us from your Son,
our Lord Jesus Christ,
who with the Father and the Holy Spirit,
lives and reigns for ever and ever.
