This verse serves as a reminder that the Gospels are not exhaustive accounts of Jesus' life and works. The miracles and teachings recorded are chosen to convey specific messages and truths about His mission and divinity. The mention of 'many other signs' suggests that Jesus' ministry was even more extensive and impactful than what is captured in the written text. This invites believers to trust in the broader scope of Jesus' work and to have faith in the unseen aspects of His life and ministry.
The Gospel writers, inspired by the Holy Spirit, selected events that would best communicate the essence of Jesus' message and purpose. This verse encourages readers to delve deeper into the meaning and implications of the recorded signs, understanding that they are part of a larger narrative of God's plan for humanity. It also emphasizes the importance of faith, as believers are called to trust in the fullness of Jesus' ministry, even beyond what is documented.
