What is the significance of the 'hour' mentioned in John 17?

'The hour' mentioned in John 17 signifies a critical moment in Jesus' ministry where He is about to fulfill the purpose for which He was sent into the world. This hour refers to the time of His suffering, death, and ultimately His glorification through resurrection. It emphasizes God's sovereignty over redemptive history; this hour had been predetermined before the foundation of the world. By acknowledging the significance of this hour, Christians understand that Christ's sacrificial death and resurrection were not accidental but part of God's divine plan for salvation. Therefore, this hour is a demonstration of God's control and purpose in glorifying His Son, thus bringing glory to Himself.
