Matthew 16:13 (NIV)
"When Jesus came to the region of Caesarea Philippi, he asked his disciples, 'Who do people say the Son of Man is?'"
Was this question for Jesus to find out something He didn't know? I do not think so. Then why did He ask this question? For whose benefit did He ask it? Did He get an answer? In fact, Jesus got a great answer, the disciples came back with a number of answers, all misconceptions that the common people had about Jesus. "Some say, John the Baptist ....or one of the prophets." His disciples had obviously been listening to the people where He had sent them on their missionary journey in the villages in Matthew chapter 10. They knew what people believed about Jesus.
My wife and I did a lot of children's evangelism in our early years of ministry. We had a large group of children from an apartment complex playground gathering for a puppet show.
