2 Timothy 2:
10 Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.
11 It is a faithful saying: For if we be dead with him, we shall also live with him:
12 If we suffer, we shall also reign with him: if we deny him, he also will deny us:
13 If we believe not, yet he abideth faithful: he cannot deny himself.
Matthew 10:33
But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.

24 Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
25 For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
Matthew 26:
33 Peter replied, "Even if all fall away on account of you, I never will."
34 "Truly I tell you," Jesus answered, "this very night, before the rooster crows, you will disown me three times."
35 But Peter declared, "Even if I have to die with you, I will never disown you." And all the other disciples said the same.
Matthew 26:
74 Then he began to call down curses, and he swore to them, "I don't know the man!" Immediately a rooster crowed.
75 Then Peter remembered the word Jesus had spoken: "Before the rooster crows, you will disown me three times." And he went outside and wept bitterly.
Matthew 27:
3 When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse and returned the thirty pieces of silver to the chief priests and the elders.

18 And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.
If there is a need to say, I'm not a Roman Catholic and I didn't say that arrogantly and selfishly.
Matthew 27:
4 "I have sinned," he said, "for I have betrayed innocent blood." "What is that to us?" they replied. "That's your responsibility."
5 So Judas threw the money into the temple and left. Then he went away and hanged himself.

12 remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world.
