1 Timothy 1:5 NASB
But the goal of our instruction is love from a pure heart and a good conscience and a sincere faith.

Romans 10:8-10 NASB
But what does it say? “The word is near you, in your mouth and in your heart” &em; that is, the word of faith which we are preaching, that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved;
for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.

Psalm 147:3 NASB
He heals the brokenhearted,
And binds up their wounds.

James 3:13-18 NASB
who among you is wise and understanding? Let him show by his good behavior his deeds in the gentleness of wisdom.
But if you have bitter jealousy and selfish ambition in your heart, do not be arrogant and so lie against the truth.
This wisdom is not that which comes down from above, but is earthly, natural, demonic.
For where jealousy and selfish ambition exist, there is disorder and every evil thing.
But the wisdom from above is first pure, then peaceable, gentle, reasonable, full of mercy and good fruits,
unwavering, without hypocrisy.
And the seed whose fruit is righteousness is sown in peace by those who make peace.

Daniel 5:20 NASB
But when his heart was lifted up and his spirit became so proud that he behaved arrogantly, he was deposed from his royal throne, and his glory was taken away from him.

Proverbs 15:28 NASB
The heart of the righteous ponders how to answer,
But the mouth of the wicked pours out evil things.

Isaiah 32:6-8 NASB
For a fool speaks nonsense,
And his heart inclines toward wickedness,
To practice ungodliness and to speak error against the LORD,
To keep the hungry person unsatisfied
And to withhold drink from the thirsty.
As for a rogue, his weapons are evil;
He devises wicked schemes
To destroy the afflicted with slander,
Even though the needy one speaks what is right.
But the noble man devises noble plans:
And by noble plans he stands.

Jeremiah 23:9-31 NASB
as for the prophets:
My heart is broken within me,
All my bones tremble;
I have become like a drunken man,
Even like a man overcome with wine,
Because of the LORD
And because of His holy words.
For the land is full of adulterers;
For the land mourns because of the curse.
The pastures of the wilderness have dried up.
Their course also is evil,
And their might is not right.
“For both prophet and priest are polluted;
Even in My house I have found their wickedness,” declares the LORD.
“Therefore their way will be like slippery paths to them,
They will be driven away into the gloom and fall down in it;
For I shall bring calamity upon them,
The year of their punishment,” declares the LORD.
“Moreover, among the prophets of Samaria I saw an offensive thing:
They prophesied by Baal and led My people Israel astray.
Also among the prophets of Jerusalem I have seen a horrible thing:
The committing of adultery and walking in falsehood;
And they strengthen the hands of evildoers,
So that no one has turned back from his wickedness.
All of them have become to me like Sodom,
And her inhabitants like Gomorrah.
Therefore thus says the LORD of hosts concerning the prophets,
‘Behold, I am going to feed them wormwood
And make them drink poisonous water,
For from the prophets of Jerusalem
Pollution has gone forth into all the land.’ ”
Thus says the LORD of hosts,
“Do not listen to the words of the prophets who are prophesying to you.
They are leading you into futility;
They speak a vision of their own imagination,
Not from the mouth of the LORD.
They keep saying to those who despise Me,
‘The LORD has said, “You will have peace” ‘;
And as for everyone who walks in the stubbornness of his own heart,
They say, ‘Calamity will not come upon you.’
“But who has stood in the council of the LORD,
That he should see and hear His word?
Who has given heed to His word and listened?
“Behold, the storm of the LORD has gone forth in wrath,
Even a whirling tempest;
I will swirl down on the head of the wicked.
“The anger of the LORD will not turn back
Until He has performed and carried out the purposes of His heart;
In the last days you will clearly understand it.
I did not send these prophets,
But they ran.
I did not speak to them,
But they prophesied.
But if they had stood in My council,
Then they would have announced My words to My people,
And would have turned them back from their evil way
And from the evil of their deeds.
“Am I a God who is “near”, declares the LORD,
“And not a God far off?
Can a man hide himself in hiding places,
So I do not see him?” declares the LORD.
“Do I not fill the heavens and the earth?” declares the LORD.
“I have heard what the prophets have said who prophesy falsely in My name, saying ‘I had a dream, I had a dream!’
“How long? Is there anything in the hearts of the prophets who prophesy falsehood, even these prophets of the deception of their own heart,
who intend to make My people forget My name by their dreams which they relate to one another, just as their fathers forgot My name because of Baal?
The prophet who has a dream may relate his dream, but let him who has My word speak My word in truth. What does straw have in common with grain?” declares the LORD.
“Is not My word like fire?” declares the LORD, “and like a hammer which shatters a rock?
Therefore behold, I am against the prophets,” declares the LORD, “who steal My words from each other.
Behold, I am against the prophets,” declares the LORD, “who use their tongues and declare, ‘The Lord declares.’

Psalm 109:20-22 NASB
Let this be the reward of my accusers from the LORD,
And of those who speak evil against my soul.
But Thou, O GOD, the Lord, deal kindly with me for Thy name’s sake;
Because Thy lovingkindness is good, deliver me;
For I am afflicted and needy,
And my heart is wounded within me.

1 Peter 3:4 NASB
but let it be the hidden person of the heart, with the imperishable quality of a gentle and quiet spirit, which is precious in the sight of God.
