This was His answer to the question: "What sign do You show us as a your authority for doing these things?" People ask for signs from God all the time. They are given on a regular basis. Just a few years ago, a group of students at St. John the Evangelist Elementary School in Jackson were participating in a monthly service of Eucharistic Adoration when they literally saw the face of Jesus appear on the Holy Eucharist. No doubt, some who had seen it have since found themselves more deeply connected to Jesus; however, some have also probably forgotten this experience. They saw a miracle and have since dismissed the moment.
We ask for signs and don't accept them when they happen or forget about them soon after.
This wasn't what I meant to write about, but it's what came out. Expect to see the quote again.
