==Structural Analysis==

From the above structural analysis, a contrast of two groups of three becomes apparent.  It is common scriptural usage to present solemn truths or warnings in groups of two, three, or four.  Examples of this include Proverbs 30; [[Amos 1:3]], 6, 9, 13 etc.; the visions of the butler and baker in Genesis 40; and the combination of Christ's words in Matthew 12:14.It is in accord with Biblical usage, therefore, to expect that in I John 5, "there are three that bear witness" will be repeated at least twice. 

The Comma is also structurally important with reference to verse 9.  I John 5:7 describes the witness of God; I John 5:8 describes the witness of men.  "If we receive the witness of men, the witness of God is greater" (5:9).Without the Comma, 5:9 has no antecedent and consequently, makes no sense.
