The faithful know how much need they have of Jesus and Him crucified; but though they wonder and rejoice at the ineffable love made manifest in Him, they are not daunted at having no more than their own poor souls to give in return for such great and condescending charity. They love all the more, because they know themselves to be loved so exceedingly; but to whom little is given the same loveth little (Luke 7:47). Neither Jew nor pagan feels the pangs of love as doth the Church, which saith, 'Stay me with flagons, comfort me with apples; for I am sick of love' (Cant. 2:5). She beholds King Solomon, with the crown wherewith his mother crowned him in the day of his espousals; she sees the Sole-begotten of the Father bearing the heavy burden of His Cross; she sees the Lord of all power and might bruised and spat upon, the Author of life and glory transfixed with nails, smitten by the lance, overwhelmed with mockery, and at last laying down His precious life for His friends. Contemplating this the sword of love pierces through her own soul also and she cried aloud, 'Stay me with flagons, comfort me with apples; for I am sick of love.' The fruits which the Spouse gathers from the Tree of Life in the midst of the garden of her Beloved, are pomegranates (Cant. 4:13), borrowing their taste from the Bread of heaven, and their color from the Blood of Christ. She sees death dying and its author overthrown: she beholds captivity led captive from hell to earth, from earth to heaven, so 'that at the name of Jesus every knee should bow, of things in heaven and things in earth and things under the earth' (Phil. 2:10). The earth under the ancient curse brought forth thorns and thistles; but now the Church beholds it laughing with flowers and restored by the grace of a new benediction. Mindful of the verse, 'My heart danceth for joy, and in my song will I praise Him', she refreshes herself with the fruits of His Passion which she gathers from the Tree of the Cross, and with the flowers of His Resurrection whose fragrance invites the frequent visits of her Spouse.
(Bernard of Clairvaux, on Loving God)
The ones who have truly felt and seen the love of God will love out of deep gratitude.
