John 15:4-16

Remain in Me, and I [will remain] in you. Just as no branch can bear fruit by itself without remaining in the vine, neither can you [bear fruit, producing evidence of your faith] unless you remain in Me. I am the Vine; you are the branches. The one who remains in Me and I in him bears much fruit, for [otherwise] apart from Me [that is, cut off from vital union with Me] you can do nothing. If anyone does not remain in Me, he is thrown out like a [broken off] branch, and withers and dies; and they gather such branches and throw them into the fire, and they are burned. If you remain in Me and My words remain in you [that is, if we are vitally united and My message lives in your heart], ask whatever you wish and it will be done for you. My Father is glorified and honored by this, when you bear much fruit, and prove yourselves to be My [true] disciples. I have loved you just as the Father has loved Me; remain in My love [and do not doubt My love for you]. If you keep My commandments and obey My teaching, you will remain in My love, just as I have kept My Father’s commandments and remain in His love. I have told you these things so that My joy and delight may be in you, and that your joy may be made full and complete and overflowing. “This is My commandment, that you love and unselfishly seek the best for one another, just as I have loved you. No one has greater love [nor stronger commitment] than to lay down his own life for his friends. You are my friends if you keep on doing what I command you. I do not call you servants any longer, for the servant does not know what his master is doing; but I have called you [My] friends, because I have revealed to you everything that I have heard from My Father. You have not chosen Me, but I have chosen you and I have appointed and placed and purposefully planted you, so that you would go and bear fruit and keep on bearing, and that your fruit will remain and be lasting, so that whatever you ask of the Father in My name [as My representative] He may give to you.
