Arguments of logic etc can only bring one to the platform of practice. If one is reluctant to take up practice there is no question of approaching evidence. It doesn't matter what field of knowledge one might be discussing.
Since there is no evidence for atheistic claims and also no practice, a majority of atheist arguments aim to deconstruct the very practices required for evidencing the nature of god.
Basically spiritual life begins at the point of understanding that one is not the body. As long as one remains in the bodily conception of life, their logic reasoning and pursuit of incentives will all be askew (even if they are a so-called theist) ... so I would argue that first one has to develop a little conviction about the unreasonable, illogical and totally uninspiring nature of considering the body as the self ... then perhaps there is the possibility of approaching spiritual life with a little determination.
Let us re-word that and say that the use of reason can bring one to reasonable conclusions. The practice involved is that of thinking. Why should one have to develop "a little conviction about the unreasonable " ? I regard that as a retrograde step. Maintaining a healthy scepticism is more to the point.
