The author imagines the reader gazing across a harbour, wondering whether now is the time to find out more about the Christian boat . What do I need to know about the invitation, the captain and the crew? Is this the right boat for the next stage of the journey? What am I looking for? If you are an open-minded enquirer, preferring to consider rather than to be pushed, or if you feel you are already on this boat but want to be reminded of some fundamentals, then this may be the book for you. It is suitable for individuals or groups.
