I John 4:14

And we--primarily, we apostles, Christ's appointed eye-witnesses to testify to the facts concerning Him. The internal evidence of the indwelling Spirit (Jo1 4:13) is corroborated by the external evidence of the eye-witnesses to the fact of the Father having "sent His Son to be the Saviour of the world." seen--Greek, "contemplated," "attentively beheld" (see on Jo1 1:1). sent--Greek, "hath sent": not an entirely past fact (aorist), but one of which the effects continue (perfect tense).

The apostle's attestation of this, in pursuance of such evidence: "We have seen and do testify. The weight of this truth obliges us to testify it; the salvation of the world lies upon it. The evidence of the truth warrants us to testify it; our eyes, and ears, and hands, have been witnesses of it." Thereupon, II. The apostle states the excellency, or the excellent privilege attending the due acknowledgment of this truth: Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God, Jo1 4:15.
