I pray.. that they may be one just as you Father are in me and I in you, that they also may be one in us so that the world may believe that you have sent me.
John 17:20-21
34 A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. 35 By this all will know that you are My disciples, if you have love for one another.
John 13:34-35
During his discussions with the disciples Jesus is looking forward to what is going to be possible after he accomplishes all that the Father has planned for him. After his death, resurrection, ascension and the sending of the Spirit, a full, eternal, unlimited love between those who have accepted his free gift of the Spirit will be possible. This is the love he wants us to experience now.
If you are part of a local church on this journey to unity you know how impossible it is. And you also know the challenge of walking in the Spirit consistently which is the only way it could ever happen.
