The theistic argument that is most powerful or persuasive to a person depends on their spirituality type. The cosmological arguments would probably appeal better to Thomistic types (like my husband), while the Augustinian types (like myself) may prefer the argument from desire and design.
For the Thomists, the argument from contingency appears convincing as the assumptions are logical and believable. William Lane Craig explains in his article, “The New Atheism and Five Arguments for God”, that this argument accepts both permanence and change. It states that for anything to be contingent in the universe, it is necessary that something (which is eternal and self-evident) is not contingent.
It is so persuasive that Dawkins does not have any response to this argument. Craig professes that this is one of the most famous arguments and is defended by philosophers such as Alexander Pruss, Timothy O’Connor, Stephen Davis, Robert Koons, and Richard Swinburne.
For the Augustinians, the teleological argument may be the most convincing. The idea that the universe was designed because it is so incredibly wonderful that the designer in question is deserving of our noble worship.
As Kant puts it: “this proof will always deserve to be treated with respect. It is the oldest, the clearest and most in conformity with human reason . . . We have nothing to say against the reasonableness and utility of this line of argument, but wish, on the contrary, to commend and encourage it.”
As such, the theistic argument that a person is most drawn to is dependent on their inclinations.
