John 4

13Jesus answered, "Everyone who drinks this water will be thirsty again, 14but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life."

I think its really cool how God tells the woman that His water will make you full and you will never thirst again. The woman is referring to the well water because Jesus asks for a drink but he then begins to explain to her how he can give her water that will make her content-that can save her and give her eternal life. He then tells her all about her own life and how she needs him. She right away realizes that she needs this "water" and believes and brings others to hear Jesus as well. I think its crazy how she believes right away and I find a lot of times in the bible where people just drop everything to follow God and I wonder how they can have such a strong faith- but it's cool!
