We really don’t know what it means to live in unity, oneness. Back in the garden when Adam and Eve sinned, separation became all we knew and still is all we know. Sin separates us from God and others. Death separates us from loved ones. We live our lives very familiar with being separated from the ones we were meant to be in unity/ oneness with here and now. It may be physical separation, emotional separation, or spiritual separation. We know nothing but separation, but Jesus came to end separation.
In this section of scripture, Jesus is praying to the Father and speaks of something that as a sinful human being seems impossible, even scandalous to believe.
“that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me.” John 17:21 ESV
Jesus speaks of Himself being one with the Father and being “in” Him. Then He prays that we are in them, the Father and the Son. We are invited into a life where separation from God is no more. We are invited to participate in His nature and to be His representative here on earth. We are invited to such closeness to God that we are one with Him: Having His mind, the mind of Christ, Having His Spirit, the Holy Spirit connecting us to Him. It is all about relationship with God, which is fellowship or friendship.
We settle for far less than we were intended to have by living after ourselves (our flesh) and not God. We want our own ways and to follow our own paths. YET We have the greatest invitation of all, to be united in oneness with God and to go with Him.
Jesus longs for us to be in Him and to experience Him fully. May our hearts cry be the same!
