Kierkegaard's Silentio contrasts the knight of faith with the other two, knight of infinite resignation and the aesthetic realm's "slaves." Kierkegaard uses the story of a princess and a man who is madly in love with her, but circumstances are that the man will never be able to realize this love in this world. A person who is in the aesthetic stage would abandon this love, crying out for example, "Such a love is foolishness. The rich brewer's widow is a match fully as good and respectable." A person who is in the ethical stage would not give up on this love, but would be resigned to the fact that they will never be together in this world. The knight of infinite resignation may or may not believe that they may be together in another life or in spirit, but what's important is that the knight of infinite resignation gives up on their being together in this world; in this life.
The knight of faith feels what the knight of infinite resignation feels, but with exception that the knight of faith believes that in this world; in this life, they will be together. The knight of faith would say "I believe nevertheless that I shall get her, in virtue, that is, of the absurd, in virtue of the fact that with God all things are possible." This double movement is paradoxical because on the one hand it is humanly impossible that they would be together, but on the other hand the knight of faith is willing to believe that they will be together through divine possibility.
The knight of faith does exactly the same as the other knight did, but he makes one more movement, for he says: Nevertheless I have faith that I will get her—that is, by virtue of the absurd, by virtue of the fact that for God all things are possible. The knight of faith can, by virtue of the absurd, get what he desires totally and completely. However, Silentio also comments that "that is over and beyond human powers, that is a marvel."
