Oneness 
The church today is divided amongst denominations and divided by strivings and self gratification. 
Jesus prayed to the Father for those who believe in Him, for oneness… the purpose was so the world believe. 

“that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.”‭‭John‬ ‭17:21‬ ‭NKJV‬‬

How will they know us, by our love (verse). We can only love the way our father desires by becoming one with Him. 
Love the lord your god…. Neighbor as your self….
