An interesting episode about the futility of taking pride in your devoutness. In reality, we deny Jesus every time we sin or hide our faith out of shame or fear.
The Apostle Peter's three denials of Christ
Luke 22 & Matthew 26
A dispute also arose among them as to which of them was considered to be greatest. Jesus said to them, “The kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors. But you are not to be like that. Instead, the greatest among you should be like the youngest, and the one who rules like the one who serves. For who is greater, the one who is at the table or the one who serves? Is it not the one who is at the table? But I am among you as one who serves. You are those who have stood by me in my trials. And I confer on you a kingdom, just as my Father conferred one on me, so that you may eat and drink at my table in my kingdom and sit on thrones, judging the twelve tribes of Israel.
“Simon, Simon, Satan has asked to sift all of you as wheat. But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers.”
But he replied, “Lord, I am ready to go with you to prison and to death.”
Jesus answered, “I tell you, Peter, before the rooster crows today, you will deny three times that you know me.”

Then seizing him, they led him away and took him into the house of the high priest. Peter followed at a distance. A servant girl saw him seated there in the firelight. She looked closely at him and said, “This man was with him.”
But he denied it. “Woman, I don’t know him,” he said.
A little later someone else saw him and said, “You also are one of them.”
“Man, I am not!” Peter replied.
After a little while, those standing there went up to Peter and said, “Surely you are one of them; your accent gives you away.”
Then he began to call down curses, and he swore to them, “I don’t know the man!”
Just as he was speaking, the rooster crowed. The Lord turned and looked straight at Peter. Then Peter remembered the word the Lord had spoken to him: “Before the rooster crows today, you will disown me three times.” And he went outside and wept bitterly.
