Jesus tells Peter he will deny he even knows Him, then He explains He is the way, the truth and the life, the only way to know the Father, and the true vine: John 13:31–38; Mark 14:27–31; Matthew 26:31–35; Luke 22:31–38; John 14:1–15:17
They already knew one of them would betray Jesus, but it didn’t get better. Now Jesus was telling Peter that He didn’t believe his promise to stay loyal:
Matthew 26:34I tell you the truth, Peter—this very night, before the rooster crows, you will deny three times that you even know me.
What a shock! Did that make him as bad as this unknown betrayer?
Matthew 26:35 No! Even if I have to die with you, I will never deny you!
The other disciples came in, of course, with a me too.
