John 15:8

Herein is my Father glorified As in John 15:6, the verb is the aorist passive; not -is being glorified" but -is glorified," i.e. whenever the occasion arises. The aorist is used of an act regarded in itself as accomplished at any conceivable moment: comp. John 17:26. -When ye pray and obtain your prayers through abiding in Me, My Father is glorified already." It is best to understand -herein" as referring to what precedes (comp. John 4:37 and John 16:30), in order to give the proper meaning to -that."

that ye bear Literally, in order that ye may bear:it is S. John's favourite particle once more, expressing the Divine purpose (comp. John 8:56; John 9:2-3; John 11:15; John 11:50; John 12:23; John 13:1-2, &c.). -Herein" cannot refer to -in order that" without awkwardness.

so shall ye be my disciples Rather, and may become My disciples. The construction introduced by -in order that" continues to the end of the verse; moreover the difference between -to be" and -to become" should be preserved (see on John 10:19; John 1:6). The sense of the whole will therefore be; -In granting your prayers My Father is glorified, in order that ye may be fruitful and become My disciples."
