In Revelations of Divine Love by the English mystic, Julian of Norwich, we find this beautiful statement about the immeasurable and incomprehensible love of God. She describes the wondrous journey of grace-enabled perseverance by which we grow in the knowledge of God’s love.
For we are so preciously loved by God that we cannot even comprehend it. No created being can ever know how much and how sweetly and tenderly God loves them. It is only with the help of his grace that we are able to persevere in spiritual contemplation with endless wonders at his high, surpassing, immeasurable love which our Lord in his goodness has for us.
