Faith is different than having a faith. A "Leap of Faith" (Kierkegaard) essentially is moving from one state to another without empirical evidence.
How do you think this Kierkegaadian
movement is made?
"[...]it repels the individual by virtue of its absurdity,[...]" - Kierkegaard
And what is the "absurd"?
"What now is the absurd? The absurd is- that the eternal truth has come into being in time, that God has come into being, has been born, has grown up, and so forth, precisely like any other individual human being, quite indistinguishable from other individuals...." - Kierkegaard
To me, at this time, it seems Kierkegaard's "leap of faith" is belief in the "absurd"
"Without risk there is no faith, and the greater the risk the greater the faith; the more objective security the less inwardness (for inwardness is precisely subjectivity), and the less objective security the more profound the possible inwardness." - Kierkegaard
"[...]there can be no stronger expression for inwardness than when the retreat out of existence into the eternal by way of recollection is impossible; and when, with truth confronting the individual as a paradox, gripped in the anguish and pain of sin, facing the tremendous risk of the ojbective insecurity, the individual believes." - Kierkegaard
