There is indeed Christian Knowledge according to Kierkegaard, in the sense that there are mental representations of the “truths” of Christianity, but possession of this “knowledge” is not sufficient to make a person a Christian… A “completely human life,” according to Kierkegaard, is not merely one of knowledge, because the medium of knowledge is thought, or ideality, whereas a human being is an interesse between thought and being, or between ideality and reality. A completely human life consists of action as well as thought, and to be really complete the action in question should represent the efforts of the individual to bring the actuality of his existence into conformity with ethical ideality.
