We can live longer without food than we can without water. Jesus said to the woman at the well, if you come back to this well you will get thirsty again, but "whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of waterwelling up to eternal life.” Jesus is able to quench our spiritual thirst like nothings else can. https://www.keyministries.net/podcast/episode/28040f77/water
