Peter felt disconnected from Jesus. Christ had been taken to the temple and he had been left alone. Instead of making an effort to get back in the presence of Jesus he decided to “reinvent” himself by acting like a completely different person. He wanted to leave his past behind and start brand new. He didn’t want to be known as a follower of Jesus. He even changed his speech so that he wouldn’t be linked to him. 
He wept when he realized what had been taking place in his life: both figuratively and literally he was running from Christ instead of to him. 
Pause today and ask the Lord which direction you are moving. He is calling you closer to him there isn’t any reason to run.
