"I do not ask for these only, but also for those who will believe in me through their word, that they may be all one,
just as You, Father, are in me, and I in You, that they may be in us, so that the world may believe that you have sent me.
The glory You have given me I have given to them, that they be one even as we are one, I in them and You in me, that they
may become perfectly one, so that the world may know that you sent me and loved them even as you loved me."
John 17:20-23
The church is to maintain the oneness that has been given by God. the family (church) is the easiest way
to do this, and the world should look in and see the supernatural oneness.
This should be the greatest evangelistic
tool in the arsenal of God's people.
Every other context of our life (including ministries) should model the principles that underpin the church, such as unity!
Ministries in the modern context have a utility in helping people see the beauty of unity by allowing people from all walks of life
and denominations to see how they can be one with followers of Christ. PERIOD.
