"The loving service of the weak and needy is an essential part of the discipline of the Christian life. Regular association with the poor, the dependent, the sorrowful, is an indispensable source of the highest elements of character. If we are faithful to the obligations which such contact with infirmity will bring; if we gently take the trembling hand that seeks our guidance, and spend the willing care, and exercise the needful patience; - why, it makes us descend into healthful depths of sorrowful affection which otherwise we should never reach." 

James Martineau.
