In Volume 4, Bill explores the Laws of the Bondservant.
Of all the commandments God gave Israel, it is the laws of the bondservant that He chose to first give them after they had asked Moses to speak to God on their behalf.
The question is:
"Why?" Also included in this volume is the teaching, "You Are What You Eat."
This delves into why God commanded what to eat and what not to eat and the implications of the dietary laws for believers in Messiah.
