700BC Part 2 – Jesus Declared. Isaiah 9 By Dusty Van Niekerk – Isaiah was a man who saw things ahead of his time.

Isaiah lived 700 years before the birth of Christ and yet he had some of the most impactful, accurate prophecies about Jesus. In this 4-week series we look at four key chapters in this amazing book – snapshots from nearly three centuries ago – that still clearly speak to us today.
