“Love God with all your heart and with all your soul” (Deut. 6:5). No one loves God except by knowing God. According to that awareness is that love; if it be a little, the love will be little; if it is abundant, the love will be abundant. It is, therefore, necessary for us to dedicate ourselves to understand and acquire intelligence in the sciences and reasonings which make known to us our Creator, in the measure of power that we possess to understand and attain it.” – Rambam, Hilchot Teshuva
