rwp@1John:2:3 @{Hereby} (\en touti\). See this phrase also in 2:5; 3:16,19,24; 4:2,13; 5:2|. That is explained by the \ean\ clause, "if we keep his commandments " (\ean trmen\, condition of the third class, \ean\ with present active subjunctive, "if we keep on keeping"), the clause itself in apposition with \touti\ (locative case). {Know we that we know him} (\ginoskomen hoti egnkamen auton\). "Know we that we have come to know and still know him," \egnkamen\ the perfect active indicative of \ginsk\. The Gnostics boasted of their superior knowledge of Christ, and John here challenges their boast by an appeal to experimental knowledge of Christ which is shown by keeping his (\autou\, Christ's) commandments, thoroughly Johannine phrase (12 times in the Gospel, 6 in this Epistle, 6 in the Apocalypse).
