Der Liebe Tun. Gesammelte Werke und Tagebücher. 19. Abt. Bd. 14

The religious speeches in this volume reveal a change in Kierkegaard's understanding of Christianity. The contrast between the Christian and the world becomes ever more pronounced; here it is emphasised in the core Christian idea of love.
love: In natural human thinking the essence of love is misinterpreted, what is understood by love there, even what the poets celebrate as the great happiness of love, is in essence rather often self-love. The contrast between such misinterpreted self-love and true Christian love for one's neighbour becomes particularly clear when the latter is relentlessly imposed on human desire for happiness.
It must use this pain to work towards turning people towards eternity; it is then 'unrecognisable' to ordinary feelings. The true nature of neighbourly love is illustrated by a multitude of different human relationships.
