Many believe that God is working with signs and miracles following all around the world. We hear of miracles in South America and Africa, but we do not experience them here at home. When we do hear of God's power in the states it is limited to a few isolated incidents, or static reports of euphoric but intangible incidents.
What part of the equation are we missing? This book may be helpful in clearing up the answers. Wigglesworth's work is completely dependent on the Bible and the lead of the Holy Spirit. Within it there is no divergence from God's inspired Word. Therefore, I find it trustworthy and useful for unlocking our understanding of God's Word.
This isn't a book to casually read in an afternoon. You'll need time to sit with it and your Bible, to study and understand what the Spirit says in the text of the Bible and the life of Smith Wigglesworth.
