Why would Christians observe festivals that would seem to be obscure Jewish Holy Days to most of mainstream Christianity? Would it surprise you to know that the human genome, and our purpose in living are intricately connected to the Holy times that God set apart in scripture? What are the biblical festivals that the apostles and the early church observed and why did they observe them? Jeff Patton searches the scriptures for the answers to these important questions, and their relevance to our worship today.
