Using hard-hitting quotes from recognized names like St. Augustine and John Bunyan, Wiersbe proves himself as a well-read author and gifted writer. The depth of his study is astounding, yet the accessibility of his text for every age group is evident as well. He proves what Luke intended-for Acts to be interpreted not as the apostles' glorious acts, but as the life-changing acts of the Holy Spirit. The same Spirit lives in believers today, the same God calls followers to expand His church, and the same basic problems still arise within the church, but the same power available then is still available now to change the nations.
