Jones takes the reader to Joshua 3 where the Isrealites are guided to the banks of the Jordan to prepare to cross into the Promised Land. The Jordan that time of year is overflowing and God has to do a miracle if He expects His Chosen to cross over. The Bible narrative says that God caused the river to pile high into a heap upstream at the town of Adam.
Scholars estimate the town of Adam was roughly nineteen miles upstream from where the Isrealites stood, far beyond where they could see. It was a miracle, but it was a miracle the people didn't witness with their own eyes. God performed the miracle upstream, out of their sight.
I believe the same situation occurs in our lives today. Here's the powerful truth:God is always at work upstream in our lives.---Brian Jones, p. 35
I'm looking forward to the rest of the book.
