“I do not ask for these only, but also for those who will believe in me through their word, 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. The glory that you have given me I have given to them, that they may 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 Great Commission given to the Church by Jesus Christ consists of proclaiming and convincing the world that God sent Jesus into the world as our Savior and Redeemer. We are commanded to make all nations His disciples. This will be fulfilled when we have “become perfectly one.” It is clear that unity in the Church is a requirement for the fulfillment of the Great Commission.
This unity and power was demonstrated in Perth, Australia when a traditional evangelical church and a full gospel church came together to host a Crusade in May 2002. In this historic meeting the Lord used believers from both churches to minister healing to the sick to confirm the gospel. As a result of the miraculous healings and the word of God, an unprecedented number of Vietnamese Buddhists and idol-worshippers came to Christ.
