Shame to Peter, so as me

Mark 14:66-72
"I don’t know or understand what you’re talking about this man" Peter disown Jesus three times.
Peter began to call down curses on himself at third time.
The rooster crowed after peter's third time denied Jesus.
Peter remembered the word Jesus had spoken to him. And he broke down and wept.
Why?
Peter is brave enough to keep within sight of Jesus as he is led away. But with nothing to do but wait, courage oozes away ad fear takes control. Three times Peter says what he swore he would ever say.
Even his leading disciple denies Jesus. But one look from his is enough to break the big fisherman's heart.
Do not swear anything before the Lord, Jesus told say yes to the truth. Peter has spiritual brave, but in body is weak.
How?
 All of us are weak as Peter. Confess my weak in flesh and pray to Jesus help me strong in spirit and walk in my way with Jesus. "The spirit is willing, but the body is weak."
