Interpretation

Jesus teaches a light of life that is worked out in work and rest in John 8:12—look for "light" and "again". Align light of life with time and attention—bind joy to obedience.

Context

John speaks here as gospel narrative writing, developing light of life. Read in John 8, its force becomes clearer. Listen for “light” alongside “again”.

Manuscripts & Textual Witnesses
The Greek text is preserved in over 5,800 manuscripts, more than any other surviving ancient work. Early papyri from the 2nd-3rd centuries like P46, P66, P75 provide text within 100–150 years of composition. Major uncial codices (Sinaiticus, Vaticanus, 4th century) contain complete or near-complete texts. The Byzantine text family represents the majority of later manuscripts. Textual variants exist but are mostly minor: word order, articles, spelling. No central Christian doctrine depends on any disputed text. Modern critical editions compare all manuscript families to determine the most likely original reading.
