The year was 325 AD. A church council had met in Nicea to settle the controversial question: Is Jesus Christ really God? The human mind struggles to understand, let alone accept, how three distinct Persons can be One: a God united in nature, character and purpose. Yet, this booklet explores the deep significance of why Jesus must be completely God to be our Saviour. It reveals a God who gave up a world of indescribable glory to live, suffer and die for helpless humans. Above all, it points us to the One in whom we can place complete trust.
