'Within' in the Bible

But whoever drinks the water that I give him will never be thirsty again. But the water that I give him will become in him a spring of water [satisfying his thirst for God] welling up [continually flowing, bubbling within him] to eternal life.”

But Jesus, aware that His disciples were complaining about it, asked them, “Does this cause you to stumble and take offense?

But now I am coming to You; and I say these things [while I am still] in the world so that they may experience My joy made full and complete and perfect within them [filling their hearts with My delight].
