In the Day of Thy Power by Arthur Wallis

Arthur Wallis (1922 1988) was an itinerant Bible teacher and author. Through his teaching and writing, most notably his book The Radical Christian (1981), Wallis gained the reputation of 'architect' of that expression of UK evangelicalism initially dubbed 'the house church movement'. He had been deeply impacted by accounts of the Revival that took place on the Isle of Lewis in 1949 which he visited. His book In the Day of Thy Power (Christian Literature Crusade: 1956) was the fruit of this visit and his subsequent studies. He wrote eleven books on themes promoting the Christian life, and travelled widely. In the Day of Thy Power is regarded by many as a classic on the topic of revival and was influential to many at the beginning of the charismatic movement in the early 1960s.
