Ultimately Peter is telling the truth. He is more than willing to lay down his life. But none of His disciples understand the magnitude of the persecution and hatred that is about to be unleashed.
Even Peter, Jesus’ dear Peter, is afraid. He protests any inference to Jesus’ impending departure. Each of the twelve would do the same. Jesus calms their fears over and over again with stories, metaphors, and outright promises, saying, “I will never abandon you like orphans; I will return to be with you” (14:18).
14 Jesus: Don’t get lost in despair; believe in God, and keep on believing in Me. 2 My Father’s home is designed to accommodate all of you. If there were not room for everyone, I would have told you that. I am going to make arrangements for your arrival.
