So then, although he knew he must die, it was not because he was the helpless victim either of evil forces arrayed against him, or of any inflexible fate decreed for him, but because he freely embraced the purpose of his Father for the salvation for sinners, as it had been revealed in Scripture.
This was the perspective of Jesus on his death. Despite the great importance of his teaching, his example, and his works of compassion and power, none of these was central to his mission. What dominated his mind was not the living but the giving of his life. This final self-sacrifice was his ‘hour’, for which he had come into the world. And the four evangelists, who bear witness to him in the Gospels, show that they understand this by the disproportionate amount of space which they give to the story of his last few days on earth, his death and resurrection. It occupies between a third and a quarter of the three Synoptic Gospels, while John’s Gospel has justly been described as having two parts, ‘the Book of the Signs’ and ‘the Book of the Passion’, since John spends an almost equal amount of time on each.
