The results to be obtained in the current study are significant in the sense that they establish the philosophical approach to religious asceticism, especially with regard to its practice by Abrahamic religions. Asceticism is not a new religious practice, as it dates back to the ancient religions and as such, understanding the background of the practice, its importance, and the reason as to why different religions practice it provides a clear framework as to why different religions have different ways of observing the practice. Therefore, understanding how these three religions operated differently, holding different beliefs and practices with regard to asceticism is critical in understanding the philosophical role of religious asceticism in Abrahamic religions. The findings of this study will be ideal in guiding believers of religious asceticism on how best to undertake this practice, in accordance with their respective religions. Furthermore, these findings will also be integral in building a philosophical understanding of the concept of religious asceticism, especially with regard to why people engage in it, its benefits and challenges, and its perceived outcomes with regard to spiritual growth, faith and beliefs, and righteousness.
