If you wonder why this is you might find out watching their 2012 Vision film (via History in the making). God, it seems, uses exceptional people to do extraordinary things and Brian Houston is perhaps one of those. The world has sung Shout for the Lord and is now crying out for the 27 million through A21 because one man was called to plant a little church in 1982.

In Indelible ink Dallas Willard describes a book about 'Famous Christians' that changed his life and I have been dipping into it over the last few years.
"I never cease to be thankful for James Gilchrist Lawson and his little book. It came at the right time and helped me see the actual presence of Jesus Christ and His kingdom and the Spirit in the real lives of real people. Thus it helped me know something of 'what is the hope of his calling, what are the riches of his glory of His inheritance in the saints, and what is the surpassing greatness of his power toward us who believe, in accordance with the working of the strength of His might which He brought about in Christ, when He raised Him from the dead and seated Him at His right hand in the heavenlies (Eph 1:18-20, authors paraphrase)
Readers should take from the reading of Lawson's book the simple but profound truth that they, too, can know by experience the truths of Christ and His kingdom that are set forth in the Bible: that if with all their heart they truly seek God, they will be found and claimed by Him. This is what human life is for."
