Satan demands access to Simon, but his perseverance is ensured by Jesus' prayer (which applies to all the disciples). Satan aims to sift the disciples, destroy their faith, and separate them from Jesus. Nevertheless, Simon's faith will continue since Jesus prayed for him, and thus he will return to Jesus after denying him. Peter is to strengthen his brothers after he returns. Peter understands that Jesus is telling him that he will not remain faithful to him but will need to return to him again. Nevertheless, Peter is adamant that he is ready to be imprisoned and die with Jesus. However, Jesus rebuts him by saying that the rooster will not crow again until Peter denies Christ three times.

Jesus has just told Peter that he will deny him. This indicates that the time of danger is upon them, and the disciples must be prepared for battle. Jesus reminds them of their previous mission, where they had everything they needed without provisions. However, as the hour of darkness approaches, they must bring provisions, including a sword. Jesus emphasizes that his life will soon fulfill Isaiah 53:12, and he will be considered a transgressor in his death. The opposition to Jesus is reaching its peak. The disciples respond that they have two swords, but their grasp of Jesus's teachings is flawed. Jesus ends the conversation, saying, "Enough of this." Their ignorance will become apparent as the story progresses.

Jesus warned the disciples about spiritual battles, and now one of the greatest battles in history is taking place at the Mount of Olives. Luke does not mention that it occurs in the garden of Gethsemane but refers to it as "the place." The disciples were encouraged to pray they would not succumb to temptation. Meanwhile, Jesus is facing his life's most significant trial and temptation. He moves a little distance away from the disciples and prays to God as his Father, asking Him to take away the cup of suffering from him. However, he ultimately submits himself to the Father's will. The authenticity of the verses about an angel strengthening him is debated, but most likely, they are original. The temptation is so intense that Jesus requires divine assistance.

The arrest of Jesus is mentioned in all four Gospels (Matt. 26:47–56; Mark 14:43–49; John 18:3–11), with Luke's account being the shortest. While warning about temptation and urging his disciples to be spiritually prepared, Jesus is suddenly confronted by a crowd led by Judas, who pretends to be a friend and approaches Jesus to kiss him. However, Jesus rebukes Judas with a question, asking if he plans to betray the Son of Man in such a hypocritical way. As Jesus' disciples saw what was happening, they asked if they should attack with a sword. One of the disciples, who was later identified as Peter in John's Gospel, swung his sword and cut off the right ear of the high priest's servant. Jesus scolded his disciple for his actions and performed his final healing. He questioned the religious authorities about why they treated him like a criminal who needed to be violently apprehended. According to Jesus' explanation, instead of arresting him in front of the crowd in the temple during broad daylight, they have chosen to capture him during the night because it's their preferred time, and the time of darkness has arrived.

The arresting band took Jesus to the high priest's house for questioning. The focus then shifts to Peter, who is confident in his ability to resist temptation. However, we learn that he is not prepared to face the dark hour, a lesson to all followers. Although Peter does not abandon Jesus initially, he does follow him at a distance and joins others around a fire in the high priest's courtyard. The message describes three instances where Peter is accused of being one of Jesus' disciples. These incidents are recorded in all four Gospels: Matthew 26:69-75, Mark 14:66-72, John 18:15-18 and 24-27. In the first accusation, a servant girl says that Peter knows Jesus, but he denies it. The second accusation is made by another person, who again claims that Peter is one of Jesus' disciples, but Peter denies it again. In the third accusation, someone says that Peter's accent gives away that he is a follower of Jesus, but Peter denies this accusation vehemently. Just as a rooster crows, the Lord casts a glance at Peter. This triggers Peter's memory of Jesus' earlier prediction, and he breaks down in tears.
