Final answer:
John 4:13 teaches that anyone who drinks the water Jesus mentions will be thirsty again, symbolizing the transient nature of earthly satisfactions compared to eternal fulfillment through spiritual means.
Step-by-step explanation:
According to John 4:13, the person who drinks the water that Jesus was talking about will be thirsty again. This verse alludes to the teaching that earthly satisfaction, represented by the water, is temporary, and only by accepting Jesus' offering, described as 'living water,' can one find eternal fulfillment that quenches spiritual thirst.
In contrast, as seen in the provided references, those who do not follow the path of righteousness may face eternal suffering, represented by the expressions of 'weeping, wailing and gnashing of teeth' in various scriptural contexts.
