The indirect approach is not a new idea in apologetics. It has been used throughout history to win over hearts and minds. Kierkegaard coined the term indirect communication and used this strategy in his writings. He wrote the following about his approach…
No, an illusion can never be destroyed directly, and only by indirect means can it be radically removed. If it is an illusion….and if there is anything to be done about it, it must be done indirectly,.... There is nothing that requires such gentle handling as an illusion, if one wishes to dispel it. If anyone prompts the prospective captive to set his will in opposition, all is lost. And this is what a direct attack achieves, and it implies moreover the presumption of requiring a man to make to another person, or in his presence, an admission which he can make most profitably to himself privately. This is what is achieved by the indirect method, which, loving and serving the truth, arranges everything dialectically for the prospective captive, and then shyly withdraws (for love is always shy), so as not to witness the admission which he makes to himself alone before God—that he has lived hitherto in an illusion (Kierkegaard, The Point of View for My Work
as an Author, p. 24ff).
Kierkegaard wrote philosophical stories, under a pseudonym, to demonstrate his ideas. Many of his stories did not provide answers, this would be a direct attack. Instead, his stories brought forth questions that pointed to Christ.
In practice, the indirect approach has been used by some of the most influential people in history. Paul at times used the indirect approach. He became "all things to all, to save at least some”. Jesus taught mostly by way of parables, which is an indirect method. In fact, Jesus’ life itself was indirect. The King of kings did not come with riches and earthly glories but was born incognito in a manger to a poor humble family. He conquered sin and death, non-directly, by submitting to the will of the Father and laying down his life on the cross. Socrates would be another example. Socrates claimed not to have wisdom, but by asking questions he was able to bring people on the journey of truth.
