I wondered if the publisher might find someone with a reputation to write a foreword. For the publisher it is a bit like an endorsement to boost sales. But for you, the reader, it is a good filter. If someone you know and trust says it’s OK then it’s worthy of your time.
Personally, I recommend God. I don’t expect the publisher to get a quote from Him, but I do expect His children to hear His endorsement. Look into His Word and listen for the witness of His Holy Spirit. This was an exciting adventure for me as it unfolded. I hope you will sense that too.
