 If you've been an unbeliever, now you change your mind and you become a believer. Notice the words of Jesus in Matthew 16, 13 through 17. When Jesus came into the region of Caesarea Philippi, he asked his disciples, saying, Who do men say that I, the Son of Man, am? And they said, Well, some think you're John the Baptist. Some say you're Elijah. Others say Jeremiah, one of the prophets.
