Perhaps unsurprisingly, there's a paradox here! Kierkegaard's own indirect communication proposes that we start with the experience of those who don't believe and meet them on their own ground. His success in doing this is evidenced by the fact that, at least for some periods of the 20th century, aspects of his work became a major focus for radical thinkers of various kinds, including the non-religious and, interestingly, a significant number of Jewish thinkers (Buber, Rosenzweig, Taubes, and others).

It seems that just Being, the sheer fact of existence, that there is something rather than nothing, already inspires a wonder akin to religion. But - as in my comment about the Kingdom of God in the last answer - Jewish and Christian traditions are also prepared to challenge what 'is' for the sake of what could be.

I think he [Heidegger] sets the question up in a useful way and, despite appearances, he's not 'against' technology. He just wants us to have a questioning and thoughtful relation to it. This must be relevant to any approach.

But why should a religious person be interested in a work like Heidegger's that many regard as the epitome of nihilism? For a start, because Heidegger forces us in a way that few philosophers do to really think through the seriousness and all-encompassing nature of our mortality.

I'm not sure that I 'am' a philosopher - but I do engage with questions that are generally recognized as philosophical questions, such as the character of human existence and what makes for a good human life.

In a sense these are questions that most people ask themselves to some extent. They become philosophical when asked with a persistence and rigour that pushes past conventional or evasive answers. It's nothing to do with acquiring a technical facility in an academic discipline.

Of course, if one's reading Kierkegaard for personal interest that's fine - but it's sloppy scholarship just to cherry pick what suits one from a particular author, whether it's Kierkegaard, Heidegger, or whoever. Nevertheless, it does seem to me that even the more religious parts of the authorship can offer significant insights into the meaning of the human condition to those who can't then say that, e.g., they believe Jesus Christ is the Son of God and their personal Saviour.
