Ask David Pitt why he writes and his answer is simple: it’s his “chance to win at least a million souls to Christ”.

Money and fame don’t matter to the spiritual author whose latest book, Yes, Relationship Really Matters, is now for sale.

“For me, it means a lot knowing that my workbook can impact people’s lives and give them the tools to develop a deeper and stronger bond with God,” he said.

“I sent my book to a publisher and they said they had never seen a workbook like this one before. They came back to me three days after receiving my manuscript and said: ‘This book is special. We need to send it around the world’.”

Yes, Relationship Really Matters is a featured book at a fair now travelling through London, England, New York, Beijing, China, Frankfurt, Germany and Guadalajara, Mexico. The tour, which wraps up on December 7, is aimed at agents, publishers and other people looking for books for libraries at universities, colleges, hospitals and other institutions.

This is Mr Pitt’s fourth book.

“For me, what’s really exciting is when someone says, ‘Can you explain the workbook to me from front to back?’” he said. “There is so much meaning in this book. Even the cover is based on verses of scripture found in Genesis 1.

“Then when you open it up, on the first pages, I tell you what the answer is to any question you might have in life or whatever it is you want to accomplish. Jesus is the answer. When we get that relationship right, everything else tends to fall into place.”

Mr Pitt was not always so eager to spread the Good News.

A near-death experience shifted his priorities.

He was deep-sea diving with friends on October 7, 1971, when the weather took a turn.

By 2.30pm, waves had risen up to three feet with ten foot swells; there weren’t any life jackets on board, nor was there a radio or flares to alert anyone to the fact they were in danger.

It took hours for them to battle the elements and get back to land; during that terrifying period, Mr Pitt made a promise to God: if He got him back home safely, he would do anything God asked him to.

Shortly afterwards Mr Pitt started to have vivid dreams about a message he felt God was trying to communicate through him. In one, he saw four Ts which eventually he discovered stood for touch, talent, time and truth — four principles he teaches about in his books.

“I guess I’m inspired to write when I have enough dreams and have enough material from those visions and dreams to start the process,” he said.

“With this latest one, I felt God reminding me that in today’s world we have so many problems because people are speaking whatever is on their mind, without really applying their heart to the situation.

“When you take what you are planning to say and use your heart to measure how it will impact others, your words have a chance to be purified.”

The goal is that readers will use his workbooks, along with the Bible, to gain a deeper understanding of spiritual principles.

Yes, Relationship Really Matters lays out 216 small steps, listed in alphabetical order from A to Z, to help people improve their one-on-one relationship with God and others.

“In the workbook, I compare people to oranges,” Mr Pitt said. “Oranges start out from seeds, just as our spiritual walk must start out with just a mustard seed of faith. When God comes along and chooses us, we turn into green oranges, which are hard, juiceless and not sweet. But when oranges are touched by the sun, just as we are touched by Jesus Christ the Son, everything changes — they become juicier, sweeter, change colour and become beneficial to others. That’s what I want people to understand: the importance of making forward progress in our faith journey and of making ourselves available to be used by God.”
