This dissertation examines the role of the fear of God in relation to the prophecy of Isaiah. The fear of God is widely known as the motto and principle regent of the Sages writings, nonetheless it is hardly known as a constant force in the writings of the prophet Isaiah, even equalising Proverbs in references to it. The latter situation is addressed to correct it as the book presents an unprecedented plethora of contexts, situations and usages of the fear of God. In view of this, semantic analysis and possible variations will be addressed in order to understand current interpretations and contrast them in light of Isaiah’s context. Additionally, an exploration of all passages expressing the fear of God was mandatory in order to find the nuances of our subject in each particular occurrence. Furthermore, Isaiah’s prophecy serves as solid background in order to examine the relationship of the fear of God and other pivotal theological themes. Finally, this thesis is analysed in view of procuring a paradigm for the Latin American evangelical Christianity, mainly Peru’s.
