In today's Gospel reading from Mark 8, Jesus asked his disciples, "Who do people say that I am?" They said in reply, "John the Baptist, others Elijah, still others one of the prophets." And he asked them, "But who do you say that I am?" Peter said to him in reply, "You are the Christ." Then he warned them not to tell anyone about him. He began to teach them that the Son of Man must suffer greatly and be rejected by the elders, the chief priests, and the scribes, and be killed, and rise after three days.
From an objective point of view, you can see that Jesus knew exactly who he was and what's going to happen to him. He first asked the disciples questions to test them. Once they knew that truth, he told them what's going to transpire. Here's nothing other than our all-knowing God being himself.
