John 14:3

ἐὰν πορευθῶ. The ἐάν does not imply a doubt; but, as in John 12:32, it is the result rather than the date of the action that is emphasized; hence ‘if,’ not ‘when.’ see on John 12:26.

ἔρχομαι κ. παραλήμψομαι. The late form λήμψομαι occurs again Acts 1:8; we have λαμψομαι Hdt. IX. 108. The change from present to future is important: Christ is ever coming in various ways to His Church; but His receiving of each individual will take place once for all at death and at the last day (see on John 19:16). Christ’s coming again may have various meanings and apparently not always the same one throughout these discourses; the Resurrection, or the gift of the Paraclete, or the presence of Christ in His Church, or the death of individuals, or the Second Advent at the last day. Comp. John 6:39-40.
