1 John 5:9 - Exposition

An argument a fortiori . If we receive expresses no doubt, but states an admitted fact gently (see 1 John 4:11 ; and comp. John 7:23 ; John 10:35 ; John 13:14 ). "If we accept human witness [and, of course, we do], we must accept Divine witness [and, therefore, must believe that the Son of God is Jesus Christ]; for the witness of God consists in this, that he has borne witness concerning his Son." Note the pertinacious repetition of the word "witness," thoroughly in St John's style. The perfect μεμαρτύρηκε indicates that the witness still continues.
