Mark 8 New International Version
Peter Declares That Jesus Is the Messiah
27 Jesus and his disciples went on to the villages around Caesarea Philippi. On the way he asked them, “Who do people say I am?”
28 They replied, “Some say John the Baptist; others say Elijah; and still others, one of the prophets.”
29 “But what about you?” he asked. “Who do you say I am?”
Peter answered, “You are the Messiah.”
30 Jesus warned them not to tell anyone about him.
Unfortunately I was unable to find the words written by Yvonne Field. It is in the UK Salvation Army song book No. 280 should you wish to look up the words.
