John 13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.

John 13:37 Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake.
John 13:38 Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.
The verse centers on "simon", "peter", "said", "lord", "whither", "goest", "thou", and "jesus". It is saying that the verse draws attention to "simon" and "peter", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 35's "By this shall all men know that..." into verse 37's "Peter said unto him Lord why cannot...", so "simon" and "peter" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "simon" and "peter" with trust shaped by these words, not by a vague optimism outside the passage.
