1 John 5:20
The context
The letter's closing paragraph, after the testimony about the water and the blood. The writer has just said that the whole world lies in the power of the evil one, and then states what the readers know: that the Son has come and given understanding.
What it establishes
It establishes that the letter ends by tying true knowledge, true deity, and eternal life to the Son, and that it addresses the readers as people who already possess this. The sentence is a summary of the letter's argument rather than a new one.
What it does not establish
It does not say plainly whom the last clause names. Whether "this is the true God" refers to the Father just mentioned or to the Son just named is a long-standing grammatical dispute, and the letter's style allows either. The verse asserts the identification without resolving the pronoun.
Short note, first pass, October 2026. Corrections welcome.
