If you believe in a concept of god which is changeless (or 'timeless') then reasoning (which involves communicating with and having the capacity to affect change in the attitudes or intentions of others) is not possible, because that involves a change (which is also prohibited by a 'timeless' existence, because change incorporates at least two distinct states, before change and after change). This is even more prominent when one incorporates characteristics of infallibility or of omniscience.
That is of course, provided you believe that simple logical examination can be performed in the abstract about such an existence.
Mind you, we see in some fables of religions with supposedly infallible, omniscient, timeless gods where that god changes their mind.... one such example would be in the Abrahamic tradition, in Exodus 32
14 i think) where God changes his mind from his previous intention to kill everyone for dancing around a statue - at least if we are to use a literal interpretation to decide to spare them.
