Jesus said to his disciples:
“I am the true vine, and my Father is the vine grower.
He takes away every branch in me that does not bear fruit,
and everyone that does he prunes so that it bears more fruit.
You are already pruned because of the word that I spoke to you.
Remain in me, as I remain in you.
Just as a branch cannot bear fruit on its own
unless it remains on the vine,
so neither can you unless you remain in me.
I am the vine, you are the branches.
Whoever remains in me and I in him will bear much fruit,
because without me you can do nothing.
Anyone who does not remain in me
will be thrown out like a branch and wither;
people will gather them and throw them into a fire
and they will be burned.
If you remain in me and my words remain in you,
ask for whatever you want and it will be done for you.
By this is my Father glorified,
that you bear much fruit and become my disciples.”

Gospel of John 15

‘Spiritual pruning takes the form of letting God eliminate the vices in our lives so that the virtues can be properly nourished. This is especially done by letting Him humble us and strip away our pride. This can hurt, but the pain associated with being humbled by God is a key to spiritual growth. By growing in humility, we grow ever more reliant upon the source of our nourishment rather than relying upon ourselves, our own ideas and our own plans. God is infinitely wiser than us and if we can continually turn to Him as our source, we will be far stronger and better prepared to let Him do great things through us. But, again, this requires that we let Him prune us. —Catholic Daily Reflections: My Catholic Life website.
