Here's my paraphrase of Mark 8:27-30:
Jesus traveled with his students to the villages of Caesarea Philippi. As they walked along the road, He asked those students, "Who are the people saying that I am?" They replied, "They think that you're just a man. Some say John the Baptist, others say Elijah, and some say that you're one of the other prophets." After hearing those answers Jesus asked them, "But who do you say I am?" Peter, who was of course the first to answer, replied, "You are the anointed one, the Messiah." And Jesus warned them not to tell anyone who He really was.
The question that Jesus asked His disciples that day was the most important question he ever asked them, and it is still the most important question for every one of us, nearly 2,000 later? Who do you say Jesus is - a good man? a great teacher? a religious leader? Or do you say that He is the Messiah, the Son of God who died to pay the penalty for you sins, and your Lord and Savior?
