The book of John provides a unique and profound perspective on the life, ministry, and divine nature of Jesus. Generally attributed to the Apostle John, who was the son of Zebedee and a member of Jesus’ inner circle. His Gospel emphasizes Jesus’ identity as the Son of God. John likely wrote his account near the end of the first century AD (around 85–90 AD), when early Christianity was expanding and facing various questions about Jesus’ identity and mission.

The geographic backdrop for much of the book is the region of ancient Israel, specifically sections of Galilee and Judea. These areas encompassed key cities such as Cana, Capernaum, and Jerusalem, each significant to Jesus’ ministry. Jerusalem served as a central religious hub, governed during Jesus’ adult life by Roman overseers, including Pontius Pilate (who ruled as prefect of Judea from 26–36 AD). Throughout the Gospel, John presents Jesus moving between Galilee and Jerusalem as He performs miracles and engages with Jewish leaders.

In John’s opening, he emphasizes the divine aspect of Christ: “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1). Through a series of signs, teachings, and discourses, Jesus demonstrates His unity with the Father and expresses His role as the true source of life and salvation. John places particular focus on Jesus’ intentional actions, such as healing the sick, feeding the multitude, and walking on water, each event pointing to His authority over creation.

The final chapters detail Jesus’ crucifixion, burial, and resurrection, culminating in the statement of purpose: “These have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name” (John 20:31). This declaration highlights why John wrote the Gospel: to urge readers toward faith in Jesus as God’s Son and to offer the assurance of eternal life to all who believe.
