Most ancient writings in Bible time were written in chiasmus (See Article Section). The structures of John's Gospel have been studied for centuries. The most complete one was offered by Ellis.
With the discipline of limiting to John's keywords, key phrases and key concepts, one can appreciate that the chiasmus' central themes and their interactions are more converged than the widely diversely opinionated commentaries.
By religiously following the actual words and wording as well as themes one can appreciate the original meaning by him or herself John's intentions readily.
Every believer should read John for him or herself at least once in this manner to figure out John's and therefore Jesus' message for now in one's own life.
As an reasonable example, I offer my own effort to inspire you to do the same.
I discover that as soon as I see the Original intentions of John, the messages in John are relevant to my daily life in the framework of the Gospel, namely the Family of God as the Trinity (Father, Son, & Spirit) embracing all believers.
Also the two Pillars of the Prologue and the Lord's prayer that support the structure of the Gospel exude the beauty of the Trinity that lives within us materially.
