Why? The Passover was a mere shadow that was only for a people before the coming of Messiah.
Christ is our Passover. When we come before Him in the truth of gospel worship we have the true Passover, not the shadowy figure that was destined to fade away along with the rest of the old covenant (Heb 8:13).
I wonder if Jesus is also angery at those who continue to worship Him according to the shadows of a faded covenant.
To learn more about how the foreshadowing was worked out by God throughout history, and experience it. I often wonder how Jesus will govern. Any ideas?
