Jesus turns water into wine everyday. Vines grow. People harvest the grapes and press out the juice. People store the juice in certain environments while microbes consume the sugar and excrete alcohol. They put the resulting liquid into bottles and pour out wine. No one is surprised.
Which do you think was easier for God? Turning water directly into wine? Or creating from nothing a world where vines miraculously grow? A world where people miraculously breath and think and eat and drink. A world where these miraculously created people utilize actual (not artificial) intelligence to discover ways to make containers that will hold grape juice. Where by their miraculously created intelligence, these people discover that the juice changes into wine. Where they discover that the juice is changed into wine by miraculously created little critters that are so small that you cannot see them. A world where they discover that there are particular ways to select grapes and ways to store the juice in certain containers at a certain temperature for a certain amount of time that results in wine that provides superior enjoyment.
Which is easier?
Why are we surprised when God changes water directly into wine instead of doing it the hard way?
