The interdependence of the body of Christ is not just a comforting thought. It is a vital factor in our spiritual life. We simply cannot make it without one another. It's true that "God has given to each man a measure of faith", but alone in isolation we will never exercise it to the full, as the context of this verse makes clear. It needs a complete body to attain the stature of Christ and to display the fullness of His glory. This is why fellowship and unity in prayer are so important. Trusting Jesus ourselves is good, but it isn't enough. We must learn to trust Him in others also. We must learn how to pray in the reality of our oneness with the brothers and sisters in Christ, for only together will we get through in prayer to God's end. We need the help of the body because we need the help of the Lord, and because His life is the life of the body we come to find that we really are better together. "For all who belong to me now belong to you. And all who belong to you now belong to me as well, and my glory is revealed through their surrendered lives. “Holy Father, I am about to leave this world to return and be with you, but my disciples will remain here.
So I ask that by the power of your name, protect each one that you have given me, and watch over them so that they will be united as one, even as we are one." John 17:10-11
