Study your heart attitude. The words we speak are linked to our true beliefs. God holds us accountable for our words.

Matthew 12:

35 A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. 36 And I tell you this, you must give an account on judgment day for every idle word you speak. 37 The words you say will either acquit you or condemn you.”

Pursue peace with those around you.

Proverbs 3:

Do not withhold good from those who deserve it
when it’s in your power to help them.
28 If you can help your neighbor now, don’t say,
“Come back tomorrow, and then I’ll help you.”
29 Don’t plot harm against your neighbor,
for those who live nearby trust you.
30 Don’t pick a fight without reason,
when no one has done you harm.
31 Don’t envy violent people
or copy their ways.
32 Such wicked people are detestable to the Lord,
but he offers his friendship to the godly.
