When Heal spoke last month at BYU's Campus Education week, he looked at the ways ancient Christians interpreted scriptures. One way of reading the scriptures, Heal said, was to find hidden messages of Christ.
Joseph was the son of Jacob who was sold into slavery by his brothers and who later became a powerful ruler in Egypt. Heal said it is one of the most beautiful stories in the Bible. Linking the story to Christ enhances that beauty.
One way of looking at the story of Joseph is to look at Joseph as a type of Christ. The story symbolically represents Jesus' life and mission.
