But who do you say that I am? Mark 8:29
There is a turning point in the ministry of Jesus in Mark’s Gospel. Prior to chapter 8, our Lord’s main emphasis was in His identity. Through His teachings, conversations, parables, and miracles, He wanted His disciples to comprehend His personhood, that He was the Messiah. In Mark 8, He took the disciples to the remote areas of Caesarea Philippi and quizzed them. “Who do [men] say that I am?” He asked. “Who do you say that I am?” Peter answered, “You are the Christ.”
Jesus abruptly changed subjects and began teaching them about His work—what He had come to do. Mark 8:31 says, “And He began to teach them that the Son of Man must suffer many things…and be killed, and after three days rise again.” In the next chapter, He repeated the lesson (Mark 9:31). In the next chapter, He explained it again (Mark 10:32-34).
These are the two foundational questions we must understand—the person and the work of Christ. Who is Jesus? What did He do?
The answers to those questions provide the basis for our entire walk of faith.
Because He was God as well as man, He was able to be the one final sacrifice for our sins. Billy Graham
