How does Joseph’s rejection by his brothers point to why Jesus had to suffer rejection?
Joseph's rejection by his brothers, who hated him and regarded him as dead, points to Jesus' rejection. Jesus likewise had to endure rejection to bring about the whole plan of salvation, die for us, and extend salvation by grace. This pattern is beautifully laid out in Joseph's life.
Les explains that when Joseph's brethren hated and rejected him and put him to death so far as they were concerned, and he ended up in Egypt, all of this shows that the Lord Jesus Himself had to go through all of these rejections in order to bring about the whole plan of salvation. That way He could die for us and extend salvation by grace. Les says this is so beautifully laid out in the life of Joseph. Joseph also told his brothers that God sent him to preserve them, showing that God is sovereign in everything He does.
