How do we know that Jesus' miracles manifest His glory?

In John 2:11, we see that the miracle performed at the wedding in Cana was not simply about creating wine but was a demonstration of Jesus' divine glory. The passage explicitly states that this was the beginning of His miracles and that through these acts, His glory was manifested. The response from His disciples—believing in Him—highlights that the miracles serve a dual purpose: they meet human needs and also point to His identity as the Son of God. Each miracle, including the transformation of water to wine, serves to deepen understanding of His grace and power, leading to an increase in faith among believers.
