Simon Peter was notorious for it...betrayal I mean. Who will ever forget how he denied three times that he knew Jesus or had any connection to Him. It was when Jesus was in the courtyard of the high priest's home during his trial. Confess that you know Jesus, don't deny Him. Acknowledge Him everywhere , and don't pretend not to know Him. Because then you'll miss God's awesome grace and love.
"Jesus said to him, "Assuredly, I say to you that today, even this night, before the rooster crows twice, you will deny Me three times."-Mark 14:30 (NKJV)
