Suffering and pleasure are among the most fundamental categories of human experience, which acquire deeper meaning and function within the realm of religion, particularly faith.  Faith, as a specific mode of human existence, plays a decisive role in how sufferings are interpreted and in the possibility of experiencing spiritual pleasure and tranquility. However, the conception of faith is not uniform across philosophical and religious traditions, and this difference has led to distinct and sometimes conflicting interpretations of the relationship between faith, suffering, and pleasure. Employing an analytical-comparative approach, this study examines the place of suffering and pleasure in the realm of faith from the perspectives of Søren Kierkegaard and Ayatollah Javadi Amoli. The comparative analysis reveals that in Kierkegaard's thought, faith, understood as an existential, personal, and risky decision, is realized in the context of anxiety, uncertainty, and "fear and trembling". Suffering plays an intrinsic role in the authenticity of the religious experience, such that the pleasure of faith is also understood within a paradoxical and unstable horizon. In contrast, Javadi Amoli views faith as grounded in the harmony of reason, human nature (fiṭrat), and revelation, which, through a rational-epistemic process, leads to nearness to God (qurb) and a stable spiritual pleasure. He interprets suffering not as an essential condition for faith, but as an educational factor and a stage on the path to human perfection. Based on this analysis, the difference in explaining suffering and pleasure in these two approaches is rooted in their divergent anthropological, epistemological, and ontological foundations. Comparing them allows for a more precise understanding of the diversity of models of faith in religious traditions.
