I see that you are FULL OF BITTERNESS.
–Acts 8:23 (NIV)–

Their mouths are FULL OF cursing and BITTERNESS.
–Romans 3:14 (NIV)–

²⁶ “In your anger do not sin”: Do not let the sun go down while you are still angry, ²⁷ and DO NOT GIVE THE DEVIL A FOOTHOLD. ²⁸ Anyone who has been stealing must steal no longer, but must work, doing something useful with their own hands, that they may have something to share with those in need. ²⁹ Do not let any UNWHOLESOME TALK come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. ³⁰ And DO NOT GRIEVE THE HOLY SPIRIT OF GOD, with whom you were sealed for the day of redemption. ³¹ GET RID OF ALL BITTERNESS, rage and anger, brawling and slander, along with every form of malice. ³² BE KIND AND COMPASSIONATE to one another, FORGIVING each other, just as in Christ God forgave you.
–Ephesians 4:26-32 (NIV)–

The fruit of the Spirit is love, joy, peace, forbearance, kindness,
goodness, faithfulness, gentleness and self-control.
–Galatians 5:22-23 (NIV)–

⁶ Moses and Aaron went from the assembly to the entrance to the tent of meeting and fell facedown, and the glory of the Lord appeared to them. ⁷ The Lord said to Moses, ⁸ “Take the staff, and you and your brother Aaron gather the assembly together. Speak to that rock before their eyes and it will pour out its water. You will bring water out of the rock for the community so they and their livestock can drink.” ⁹ So Moses took the staff from the Lord’s presence, just as he commanded him. ¹⁰ He and Aaron gathered the assembly together in front of the rock and Moses said to them, “Listen, you rebels, must we bring you water out of this rock?”¹¹ Then Moses raised his arm and struck the rock twice with his staff. Water gushed out, and the community and their livestock drank. ¹² But the Lord said to Moses and Aaron, “Because you did not trust in me enough to honor me as holy in the sight of the Israelites, you will not bring this community into the land I give them.” –Numbers 20:6-12 (NIV)

He bids him speak to the rock, which would do as it was bidden, to shame the people who had been so often spoken to, and would not hear nor obey. Their hearts were harder than this rock, not so tender, not so yielding, not so obedient. He promises that the rock should give forth water (Numbers 20:8), and it did so (Numbers 20:11): the water came out abundantly…Moses and Aaron acted improperly in the management of this matter, so much so that God in displeasure told them immediately that they should not have the honour of bringing Israel into Canaan, Numbers 20:10-12…They said and did all in heat and passion; this is the account given of the sin (Psalms 106:33): They provoked his spirit, so that he spoke unadvisedly with his lips. It was in his passion that he called them rebels. It is true they were so; God had called them so; and Moses afterwards, in the way of a just reproof (Deuteronomy 9:24), calls them so without offence; but now it came from a provoked spirit, and was spoken unadvisedly: IT WAS TOO MUCH LIKE RACA, and THOU FOOL. His smiting the rock twice (it should seem, not waiting at all for the eruption of the water upon the first stroke) shows that he was in a heat. The same thing said and done with meekness may be justifiable which when said and done in anger may be highly culpable; see James 1:20…That the best of men have their failings, even in those graces that they are most eminent for. The man Moses was very meek, and yet here he sinned in passion; wherefore let him that thinks he stands take heed lest he fall. That God judges not as man judges concerning sins; we might think that there was not much amiss in what Moses said and did, yet God saw cause to animadvert severely upon it. He knows the frame of men’s spirits, what temper they are of, and what temper they are in upon particular occasions, and from what thoughts and intents words and actions do proceed; and we are sure that therefore his judgment is according to truth, when it agrees not with ours. –MATTHEW HENRY

What was the offence for which Moses was excluded from the promised land? It appears to have consisted in some or all of the following particulars:

1. God had commanded him (Numbers 20:8) to take the rod in his hand, and go and SPEAK TO THE ROCK, and itshould give forth water. It seems Moses did not think speaking would be sufficient, therefore he smote the rock without any command so to do.

2. He did this twice, which certainly in this case indicated a great perturbation of spirit, and want of attention to the presence of God.

3. He permitted his spirit to be carried away by a sense of the people’s disobedience, and thus, being provoked, he was led to speak unadvisedly with his lips: Hear now, ye REBELS, Numbers 20:10.

4. He did not acknowledge GOD in the miracle which was about to be wrought, but took the honour to himself and Aaron: “Must WE fetch you water out of this rock?”

Thus it plainly appears that they did not properly believe in God, and did not honour him in the sight of the people; for in their presence they seem to express a doubt whether the thing could be possibly done. As Aaron appears to have been consenting in the above particulars, therefore he is also excluded from the promised land. –ADAM CLARKE

I believe the Bible allows for prophets, preachers, and evangelists to express righteous indignation in sermons, but only in a punctuated short little outburst, and only in such a way that communicates urgent warning and grief over sin, expressing God’s anger and grief over the sin of the people of God. Jeremiah was full of the fury of the Lord (6:11), Jesus was so grieved at the Pharisees that he gave them all an angry look right before he healed a person (Mark 3:5), and Paul rebuked Elymas with an angry outburst after being filled with the Holy Spirit and just before prophesying him into blindness (Acts 13:8-11). There’s also occasions of Isaiah, John the Baptist, Jesus, and Paul saying what some people might consider to be pretty mean and hurtful things. But they are rebukes! Words of correction! Words of repentance! And they come from godly hearts filled with grief, holy anger, urgency, and warning:

CRY ALOUD, SPARE NOT, LIFT UP THY VOICE LIKE A TRUMPET, and shew my people their transgression, and the house of Jacob their SINS! –Isaiah 58:1 (KJV)

O GENERATION OF VIPERS, who hath WARNED YOU to FLEE FROM THE WRATH TO COME!? –Matthew 3:7 (KJV)

WOE UNTO YOU, scribes and Pharisees, HYPOCRITES!   –Matthew 23:13 (KJV)

THOU CHILD OF THE DEVIL, thou enemy of all righteousness, wilt thou not cease to PERVERT THE RIGHT WAYS OF THE LORD!? –Acts 13:10 (KJV)

Such outbursts could only come from the hearts of men that loved God with all their hearts, souls, minds, and strength; and who also loved their neighbors as themselves, and were not so hard-hearted as to just let them pass through life and go to Hell unwarned. Apathy and unbelief does not warn. Love, concern, and faith does. But sadness and weeping, it seems, is more near to the heart of God than his wrath, although both of them are attributes of God’s Spirit. What theologian would make the case that Hell was only created from the attribute of God’s sadness rather than mainly of his wrath? No Bible believing theologian would defend such a view. But it seems that the complication Moses experienced in Numbers 20:10-11 was that while he was sold out in his fear and love for the Lord; he was also constantly provoked by people who did not fear, nor believe, nor love God. And so, while Moses probably had many times like Isaiah, John the Baptist, Jesus, and Paul, where he issued a loud rebuke with holy anger that came from the heart of God–this time it was different. And it seems that the difference was one of PURE HATE! Moses HATED these people; and he expressed his hate, as he operated in the gift of prophecy and miracles at the same time. God was about to do a miracle of providence and mercy and love; and Moses spoiled the event as he expressed his PURE HATRED for all of them, as he worked the miracle. He said: “’Listen, you rebels, must we bring you water out of this rock?’ Then Moses raised his arm and struck the rock twice with his staff” (Num. 20:10-11). That’s where Moses messed up. He lost his composure and self-control, so much so, that he didn’t just REBUKE and WARN them as Isaiah, John the Baptist, Jesus, and Paul did. Moses went further than rebuking and warning. Moses expressed hatred towards them–and while he was working a miracle of God’s provision–he said, “You rebels!” and then struck the rock twice like a baseball bat in a fit of anger. This shows us that he HATED these people, was FED UP with them, and COULDN’T STAND THEM ANYMORE!! –J.B.

How awful are those words, which are the words of the great God. “I will tread them in mine anger, and will trample them in my fury, and their blood shall be sprinkled upon my garments, and I will stain all my raiment” (Isaiah 63:3). It is perhaps impossible to conceive of words that carry in them greater manifestations of these three things, viz. contempt, and hatred, and fierceness of indignation. If you cry to God to pity you, he will be so far from pitying you in your doleful case, or showing you the least regard or favor, that instead of that, he will only tread you under foot. And though he will know that you cannot bear the weight of omnipotence treading upon you, yet he will not regard that, but HE WILL CRUSH YOU UNDER HIS FEET WITHOUT MERCY; HE WILL CRUSH OUT YOUR BLOOD, AND MAKE IT FLY, and it shall be sprinkled on his garments, so as to stain all his raiment. He will not only hate you, but he will have you in the utmost contempt: no place shall be thought fit for you, but under his feet to be trodden down as the mire of the streets.  –Jonathan Edwards, “Sinners in the Hands of an Angry God,” 2.2
