Maimonides equated the God of Abraham to what philosophers refer to as the Necessary Being. God is unique in the universe, and the Torah commands that one love and fear God (Deut 10:12) on account of that uniqueness. To Maimonides, this meant that one ought to contemplate God's works and to marvel at the order and wisdom that went into their creation. When one does this, one inevitably comes to love God and to sense how insignificant one is in comparison to God. This is the basis of the Torah.
