This book traces the argument made by theHoly Spirit, speaking through the Apostle Paul, about the normal development of a Christian, from his first realization of his guilt before God, to full maturity in Christ. Then it traces the HolySpirit's argument about the irrevocable nature ofGod's promises to the ancient nation of Israel, and how that demonstrates the absolute reliability of all of His promises. And then it traces the outworking of these truths in practical Christian living.
