“Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit.”
King James Version (KJV)
15:2 Every one that beareth fruit, he purifieth - by obeying the truth, #1Pet 1:22|; and by inward or outward sufferings, #Heb 12:10|,11. So purity and fruitfulness help each other. That it may bear more fruit - For this is one of the noblest rewards God can bestow on former acts of obedience, to make us yet more holy, and fit for farther and more eminent service.
Joh 15:2 Every branch in me that beareth no fruit he taketh away. As the husbandman cuts off the unfruitful branches of the vine, so the Father severs the unfruitful branches from his Son. Judas, an unfruitful branch which did not have the life of the Vine, had just been severed and had gone forth. Every [branch] that beareth fruit, he purgeth it. The husbandman prunes and dresses the branches in order that they may be more healthy and fruitful. The Father cleanses, purifies, frees from sin, all who become branches of the True Vine.
