George Macdonald said this quote

she had no stay, no root in herself yet. Well do I know not one human being ought, even were it possible, to be enough for himself; each of us needs God and every human soul he has made, before he has enough; but we ought each to be able, in the hope of what is one day to come, to endure for a time, not having enough. Letty was unblamable that she desired the comfort of humanity around her soul, but I am not sure that she was quite unblamable in not being fit to walk a few steps alone, or even to sit still and expect. […] and now her heart was like a child left alone in a great room. She had not yet learned that we must each bear his own burden, and so become able to bear each the burden of the other. Poor friends we are, if we are capable only of leaning, and able never to support.
