Jesus was fresh on the scene. He and the boys were invited to a wedding but there was a scandal brewing – supplies were running out. This “skandaal” would embarrass the happy couple forever. Then Jesus’ Mom stepped in to help and said these words of eternal consequence, “Whatever he tells you, do it” (John 2:5 – https://bit.ly/3hOBUXF).
Mary knew the answer to that great question in Genesis 18:14, “Is anything too hard for the Lord?” – that, “With man, this is impossible but with God, all things are possible” (Matthew 19:26 – https://bit.ly/34SWWgV).
As a result, his disciples believed, trusted in and relied on him.
