Overall organized religion is simply designed to put one on a path to G-d.  Judaism is not a system with mandatory beliefs about G-d.  Rather, one is encouraged to explore their relationship to the "Great Mystery."  It is a life-embracing compass with practices which include prayer (communication with G-d), rituals (methods to tap into the subconscious) and ways to interact with G-d and with humans (kindness, justice, forgiveness and a way to spiritual evolve). 

Organized religion, at its optimal, is a group whose mission is to experience G-d.  Without the trail of breadcrumbs left by Sages, it would be nearly impossible to chart a direct course to G-d.  Thus, our Sages instituted a law saying "Do not separate yourself from the group." (Pirkey Avot 2:5).  They also note that G-d always hears the prayers of the community.   (Yad HaChazaka, Laws of Prayer 8:1).  We are better together working as a team.
