Here is an old book that is in the public domain (copyright expired), called Lectures on Calvinism by Abraham Kuyper. Kuyper was once Prime Minister of the Netherlands. He was Reformed, specifically Dutch Reformed, and was also a theologian and pastor.
The book covers what a Reformed, and hence biblical, outlook should be. This book began as an 1898 “Stone Lectures series” which Kuyper gave at Princeton University.
Famous Reformed apologist Cornelius Van Til (who used presuppositional apologetics) was influenced by Kuyper and others who were Dutch Reformed.
