'Love is the crossbearing strength of true affection'
This quote comes from a book called, The Wondrous Passion by F.W. Drake and was written for Lent. It was published just before the outbreak of the Great War in 1912. According to the Bishop of London in his introduction, it is meant to be read slowly.
The quote gets at the heart of true love. There is a affection, but also a willingness to bear pain. And there is strength. I guess any faithful parent would be able to tell you this.
