This is one of my favorite songs of all times, especially since it speaks about the source of our oneness. We are not one because of any outward unity or agreement, but it is the Triune God who included us in His divine oneness! How wonderful is that! People in the world want to obtain oneness and seek all kinds of outward things or activities in which they can be one... - this is outward, it passes away, and is NOT the real oneness! The real oneness in this universe is the oneness of the Triune God enlarged to include humanity - we can be one in God's life!
Oneness is not outward unity but the Triune God including us in His divine Oneness!
Oneness is NOT unity, outward agreement,What is oneness? It is not something we decide to do and not even something that the circumstances or our family constrains us to have - no, it is the Triune God, who is One, bringing us into Himself! Oneness is a life within - God's life, the life of oneness, coming into us and living into us, bringing us into the divine oneness! There's no way for us human beings to be one - unless it is unto evil. But God is Triune and He is One - He is the Father, the Son, and the Spirit, Three Yet One, One yet Three, ONE! This is His main attribute, the most outstanding characteristic - God is One!
But a life within - God's very life,
The Triune God included us
In His divine oneness! ONENESS!
Chorus: That they all may be one!
Even as You, Father,
Are in Me, and I in You!
That they may be - may be in Us!
Oneness! Oneness!
And in John 17:21 the Lord Jesus prayed for the disciples to be one just as the Son is in the Father and the Father is in the Son! What kind of a oneness is this? This is the Oneness of the Triune God - God the Father being one with God the Son and with God the Spirit, even the Father being IN the Son and IN the Spirit - now this oneness, which no man can understand, reproduce, or imitate, is enlarged to include us! We are in Christ, who is in the Father - we are ONE!
And, as a footnote / side note, we have enjoyed this song so much in the 2009 Winter School of truth in London, UK (see the youtube video of that)! Since then, though we may sing this song many times, we are bring brought into this deep realization - the Triune God included us in His divine oneness, and the deep desire in God's heart is being accomplished by us being in our mingled spirit, where the oneness is! Hallelujah, ONENESS!
