This little book was published as a series of articles in the Indian Witness with special reference to the Evangelistic Campaign now going on in the Indian Church. It met with such a wide appreciation that it was decided to publish it in book form as soon as possible, so that it might be permanently useful to all Christians seeking to do a more intensive and fruitful personal work. Just after receiving the manuscript from Howard Walter we learnt the news that he had been called away to the higher, nobler tasks in the world beyond. We are very grateful to the Editor of the Indian Witness, for his kindness in permitting the publication.
