{Should know} (gin(9373)k(9373)in). Present active subjunctive
with hina (subject clause), "should keep on knowing." {Even
Jesus Christ} (I(8873)oun Christon). See  1:17  for the only other
place in John's Gospel where the words occur together. Coming
here in the Lord's own prayer about himself they create
difficulty, unless, as Westcott suggests, Christon be regarded
as a predicate accusative, "Jesus as the Christ" (Messiah).
Otherwise the words would seem to be John's parenthetical
interpretation of the idea of Jesus. Lucke thinks that the
solemnity of this occasion explains Jesus referring to himself in
the third person. The knowledge of "the only true God" is through
Jesus Christ ( 14:6-9 ).
