The human being can have MANY "emotions" ("emotions" are not the same as SENTIMENT).
The LIVING WATER that God encourages us to have means that we shall have a genuine CARING "heart of FLESH" (instead of an indifferent/uncaring heart of stone).......this is so we "neither thirst".
Eze 36:26 A new heart I will give you, and a new spirit I will put within you; and I will take out of your flesh the heart of stone and give you a heart of flesh.
Eze 11:19 And I will give them one heart, and put a new spirit within them; I will take the stony heart out of their flesh and give them a heart of flesh,
Jhn 7:38 He who believes in me, as the scripture has said, 'Out of his heart shall flow rivers of living water.'"
Rev 7:16 They shall hunger no more, neither thirst any more; the sun shall not strike them, nor any scorching heat
Isa 49:10 they shall not hunger or thirst, neither scorching wind nor sun shall smite them, for he who has pity on them will lead them, and by springs of water will guide them.
Eze 16:49 Behold, this was the guilt of your sister Sodom: she and her daughters had pride, surfeit of food, and prosperous ease, but did not aid the poor and needy
God doesn't expect us to NOT BE HUMAN BEINGS, He wants us to OVERCOME/overpower "the flesh" handicap that prevents Godliness.
In verse 49, God lets us know the REAL reason He faulted Sodom and Gommorah.
Eze 16:50 They were haughty, and did abominable things before me; therefore I removed them, when I saw it.
"Emotions" are not BAD, but they will MISGUIDE us.
Our hearts must contain SENTIMENT and control/effect our MINDSET.
