Thirsting After Righteousness?

Blessed are they which do hunger and thirst after righteousness: for they shall be filled.
Matthew 5:6

Jesus answered and said unto her, Whosoever drinketh of this water shall thirst again: But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
John 4:13,14

In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.  He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
John 7:37-39
