Jesus is a central figure in The Flying House, appearing throughout the series as the anchor for the time-traveling adventures of the protagonists. The character is portrayed as the Messiah whose life, from birth to ascension, is witnessed firsthand by the children from the 20th century. His depiction is reverent and largely faithful to the New Testament narrative, adapted for a young audience.

The story of Jesus in the series begins before his earthly life. The main characters are present for the announcement of his impending birth by the angel Gabriel, which is recounted when they later find the newborn in a manger in Bethlehem. Following this, they encounter Jesus as a twelve-year-old in the Temple in Jerusalem, demonstrating his early wisdom and understanding. The narrative then progresses through his adult ministry, where the children witness his baptism by John the Baptist, his temptation in the wilderness by Satan, and his calling of the twelve disciples, including Matthew the tax collector.

Throughout his public ministry, the character is defined by his teachings and miraculous abilities. Jesus is shown delivering many of his most famous parables, such as the Good Samaritan, the Prodigal Son, the Good Shepherd, and the Sower. His power over nature, illness, and death is demonstrated through numerous miracles, including turning water into wine at a wedding in Cana, feeding five thousand people with five loaves and two fishes, healing a centurion's servant, casting out demons from the Gerasene demoniac, raising Jairus' daughter and Lazarus from the dead, and healing a paralytic man. These events are presented not merely as historical reenactments but as educational moments for Justin, Angie, and Corky.

The personality of this portrayal is consistent with the biblical source material, projecting an aura of patience, wisdom, compassion, and divine authority. His motivations are to fulfill his spiritual mission, teach about the Kingdom of God, and show love and redemption to humanity. This is particularly evident in episodes that focus on forgiveness, such as his interaction with the woman taken in adultery, his acceptance of Zacchaeus the tax collector, and his promise of paradise to the thief on the cross.

A key aspect of the series is the relationship between Jesus and the children. They literally watch him grow from an infant to an adult, creating a bond of familiarity and deep emotional investment. This connection reaches its dramatic peak during the final days of his life. The children are present for his triumphant entry into Jerusalem, the Last Supper where he washes the disciples' feet, his agonizing prayer in the Garden of Gethsemane, his betrayal by Judas Iscariot, and his denial by Peter. The show does not shy away from the climax of his mission. Episode forty-one, titled Golgotha, depicts the crucifixion in a manner described as a heartbreaking watch, as the children and the robot S.I.R. witness the man they have grown up with carry his cross to be executed. His death is presented as a profound moment of sorrow for all the main characters. However, the narrative continues to his resurrection and the discovery of the empty tomb, culminating in his ascension to heaven, which serves as the final act of his earthly journey within the series.

In terms of development, the character remains constant in his divine nature and purpose. The growth is seen in the progression of his public ministry from a teacher and healer to the sacrificial savior. His notable abilities are the full range of biblical miracles, which serve to establish his identity as the Son of God. The series does not create new fictional powers for him but instead adapts the canonical stories for its educational and spiritual purpose, making him the unwavering center of the historical events the flying house visits.
