If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.
In the context, Jesus is telling his disciples, and all of us who would follow him that his words remaining in us have to do with keeping as in obeying his commands. And that his command is that we’re to love each other. Of course we know that all of his commands are important. And as James tells us, we’re not only to hear the word, but do it, put it into practice.
The promise here is remarkable, actually, and for everyone who is a follower of Jesus. We’re simply to remain (or, abide) in him and his words are to remain in us. And this needs to be seen in the entirety of the passage, about the true vine and the branches. We are the branches in the true vine who is Jesus. The Father, who is the gardener in this (at least kind of) parable cleanses as in prunes such plants. It is a process which is involved in us being united to Jesus.
The end result is bringing the Father glory by showing oneself to be in the Son in bearing much fruit. The fruit spoken of here, is the fruit that is eternal, that is meant both for this life and beyond, for the life to come.
And so, as I start a new (work) week, I want to remind myself again of the point of it all: being changed more and more into the likeness of our Lord, yes together with others in him, as we love each other in and through Jesus as a witness to the world. And as a result of God’s good, if sometimes painful work in us, in and through Jesus.
