takes away (v.2) = should be “lifted up.” Caused to bear fruit.
prune (v.2) = cleanses — washes off parasites, with the water of the Word. To make them more fruitful (not to make fit for heaven).
already (v.3) — “standing” as opposed to “state” in the previous verse
The true branches are cleansed/purged by the Word (v.3).
abide (v.4) — (used 15 times in John 15:1-10) union, oneness, the continuing activity of faith
he who (v.5) — the 11 disciples, all saved.
does not abide in Me (v.6) — unbelievers, those who claim to be of the vine but aren’t. This isn’t loss of salvation. Note the change of address in verse 6 — not “ye” but “anyone.”
ask what you desire (v.7) — in accordance with fruit-bearing and glorifying God, asking that they will be aligned with His will. Specifically to the disciples.
All my commentaries begin by showing that in Scripture, the vine is Israel. But then they insist on reading the Church into the passage. Why? John wrote it (Galatians 2:9). Christ was talking to the disciples who were all Jewish. Although it can certainly apply to the Church in many ways, it’s essential reference is Israel.
