Christ does signs or miracles. Hungry people receive food. The blind see. The lame walk. Sick folks get well.
Disciples learn the way of the cross.
And believers start pouring into the fold. More importantly, signs point beyond the event itself. Signs in the Gospel of John are designed to help humankind see life as God sees it. Our Lord spends an inordinate amount of time in close conversation, dialogue and debate with those who seek knowledge and those who want to trap him. Space is provided for understanding and being understood.
