This is a compilation of excerpts from various writings of Kierkeegaard, arranged under specific thematic headings. Reading this served to be very edifying and convicting. Soren Kierkegaard is considered the father of modern existentialist philosophy (or more specifically Christian Existentialism), and I was able to more thoroughly understand his views through reading this (and to more specifically realize that many - but definitely not all - of his thoughts are simple restatements of New Testament teachings).
I previously assumed that Kierkegaard's existentialism focuses solely on the preeminence of subjective truth to the individual at the expense of objective truth (which when taken absolutely, I don't agree with), but what I found Kierkegaard's writings to mostly emphasize is the importance of both. He affirms that there is an absolute, objective truth that exists with respect to God and all of reality, but that God must be experienced and KNOWN subjectively (that is through a personal, spiritual relationship that informs and impacts our will). It is the difference between understanding the gospel and EXPERIENCING the gospel, and it is this EXPERIENCE that Kierkegaard argues was being ignored by many in the church of his day.
This work covers many themes of which Kierkegaard elegantly and cleverly writes on and details. His writing is sometimes encouraging/uplifting, sometimes cutting/convicting, and sometimes sarcastic/comedic. He writes heavily on such topics as the importance of the individual over the collective, the importance of following Christ and not being merely an "admirer", the extremely high call to which Christ calls his followers (total sacrifice of worldly things and selflessness, to which he admits that he himself fails at), the nature of love and the command to love ones neighbor (he has some particularly beautiful passages on this topic...including many that rival the prose of such authors as C.S. Lewis), the nature of spiritual anxiety/despair, and many other topics.
Some Example Quotes that portray ideas of his "Christian Existentialism":
"We are not saying that to need God is to sink into a dreaming admiration and some visionary contemplation. No. God does not let himself be taken in vain in this way. Just as knowing ourselves in our own nothingness is the condition for knowing God, so knowing God is the condition for the sanctification of a human being by God's assistance and according to his intention. Wherever God is, there he is always creating. He does not want a person to be spiritually soft and to bathe in the contemplation of his glory. He wants to create a new human being. To need God is to become new. And to know God is the crucial thing. Without this knowledge a human being becomes nothing. Without this knowledge, he is scarcely able to grasp that he himself is nothing at all, and even less that to need God is his highest perfection."
"What I really lack is to be clear in my mind what I am to do, not what I am to know, except in so far as a certain understanding must precede every action. The thing is to understand myself, to see what God really wants me to do. The thing is to find a truth that is true for me, to find the idea for which I can live and die. What would be the use of discovering so-called objective truth, of working through all the systems of philosophy and of being able, if required, to review them all and show up the inconsistencies within each system; what good would it do me to be able to develop a theory of the state and combine all the details into a single whole, and so construct a world in which I did not live, but only held up to the view of others; what good would it do me to be able to explain the meaning of Christianity if it had no deeper significance for me and for my life; what good would it do me if truth stood before me, cold and naked, not caring whether I recognized her or not, and producing in me a shudder of fear rather than trusting devotion?
I certainly do not deny that there is an imperative of understanding, but it must be taken up into my life, and that is what I now recognize as the most important thing. That is what I lack, and that is why I am left standing like a man who has a rented house and gathered all the furniture and household things together, but has not yet found the beloved with whom to share the joys and sorrows of his life."
