Some commentators refer to this ending as a colophon.690However, it is more similar to a postscript because it contains only hints of the writer's identity. Mainly it claims that this Gospel is a reliable though limited record of Jesus' actions.
21:24 Most careful students of this Gospel have deduced from this and other oblique references in the book that the Apostle John is the writer in view. This description of the writer stresses the reliability of his witness.691"These things"probably refers to the whole Gospel, not just what immediately precedes. The statement is general, and it occurs at the end of the book.
The identity of the "we"is less clear. They could be writers who recorded John's verbal witness as he dictated the material in this Gospel to them. They could be editors of the Gospel. Some scholars view these people as the elders of the Ephesian church where John traditionally served late in his life.692Others believe that they were influential men in his church though not necessarily in Ephesus.693Another view is that this is an indefinite reference similar to "as is well known."694Probably John himself wrote this statement in the plural, as authoritative people sometimes do. It would then be an editorial "we"(cf. 1:14; 3:2, 11; 20:2; 1 John 1:2, 4, 5, 6, 7; 3 John 12). Since the next verse returns to the first person, this option seems most probable to me.
21:25 This final verse along with the one preceding it returns to the broad perspective with which this Gospel began in its prologue (1:1-18). The prologue presents the Word humbling Himself and entering the world in incarnation. This verse presents the world as not able to contain all the revelation that the Word made. John's final word was that what he wrote, and what everyone else could write, would be only a small part of what could be written to bring honor to Jesus Christ.
