Strong was a pioneer progressive, outlining an understanding of the Christian religion that was a hundred years ahead of the current progressive Christian movement in Australia. His goal, he said, was to 'Re-interpret Christianity in the light of modern knowledge, the principles of development, and the spirit of religion as distinguished from the letter; to re-interpret Christianity just as Copernicus and Galileo re-interpreted astronomy.' Strong's focus was on knowing the Spirit as a universal all-animating Spirit, an eternal and deep dimension of reality within humans as well as nature. The Kingdom of God is really The Kingdom of Love; love is the force of God at work in humans to change society. This volume reprints five sermons published originally in 1894, sermons which reflect his progressive approach to spirituality and faith.
