The Apostle Paul taught the people in the churches which he planted that God had saved them in order to come and live inside them through his Holy Spirit. In 49AD, Paul wrote his letter to the Galatians to teach them how the Holy Spirit makes people free on the inside. In 60AD, he wrote to the Ephesians to explain how the Holy Spirit made people new on the inside, and to the Colossians to teach them how the Spirit makes people strong on the inside too. In 61AD, he wrote to the Philippians to teach them how the Holy Spirit makes people joyful on the inside. The Straight to the Heart of series of devotional commentaries allow people to get to grips with each book of the Bible one bite at a time. Phil Moore does not cover the whole of each book, but rather focuses on key sections which together form a useful introduction. There will be 25 volumes in all, each containing 60 readings. The short chapters are punchy and relevant, yet crammed with fascinating scholarship.
