Jesus teaches union with himself

15 ^1-8 “I am the real vine, my Father is the vine-dresser. He removes any of my branches which are not bearing fruit and he prunes every branch that does bear fruit to increase its yield. Now, you have already been pruned by my words. You must go on growing in me and I will grow in you. For just as the branch cannot bear any fruit unless it shares the life of the vine, so you can produce nothing unless you go on growing in me. I am the vine itself, you are the branches. It is the man who shares my life and whose life I share who proves fruitful. For the plain fact is that apart from me you can do nothing at all. The man who does not share my life is like a branch that is broken off and withers away. He becomes just like the dry sticks that men pick up and use for the firewood. But if you live your life in me, and my words live in your hearts, you can ask for whatever you like and it will come true for you. This is how my Father will be glorified—in your becoming fruitful and being my disciples.

^9-15 “I have loved you just as the Father has loved me. You must go on living in my love. If you keep my commandments you will live in my love just as I have kept my Father’s commandments and live in his love. I have told you this so that you can share my joy, and that your happiness may be complete. This is my commandment: that you love each other as I have loved you. There is no greater love than this—that a man should lay down his life for his friends. You are my friends if you do what I tell you to do. I shall not call you servants any longer, for a servant does not share his master’s confidence. No, I call you friends, now, because I have told you everything that I have heard from the Father.

1 ^1-4 We are writing to you about something which has always existed yet which we ourselves actually saw and heard: something which we had an opportunity to observe closely and even to hold in our hands, and yet, as we know now, was something of the very Word of life himself! For it was life which appeared before us: we saw it, we are eye-witnesses of it, and are now writing to you about it. It was the very life of all ages, the life that has always existed with the Father, which actually became visible in person to us mortal men. We repeat, we really saw and heard what we are now writing to you about. We want you to be with us in this—in this fellowship with the Father, and Jesus Christ his Son. We must write and tell you about it, because the more that fellowship extends the greater the joy it brings to us who are already in it.
