Straight to the Heart of Acts - STTH by Phil Moore and published by Monarch Books.
In 30 AD, Jesus of Nazareth looked to have been an utter failure. If you don't understand that, then you will miss the message of the book of Acts. It is a record of survival through adversity, triumph against all odds, and victory snatched from the jaws of defeat. It is the story of a group of ordinary people who turned the tide of history through the power of their extraordinary God.
Straight to the Heart of Acts is one of a series of devotional commentaries, which 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.
