Warn a divisive person once, and then warn him a second time. After that, have nothing to do with him.
Titus 3:10 (NIV)
A worthless person, a wicked man,
goes about with crooked speech,
winks with his eyes, signals with his feet,
points with his finger,
with perverted heart devises evil,
continually sowing discord;
therefore calamity will come upon him suddenly;
in a moment he will be broken beyond healing.
There are six things that the LORD hates,
seven that are an abomination to him:
haughty eyes, a lying tongue,
and hands that shed innocent blood,
a heart that devises wicked plans,
feet that make haste to run to evil,
a false witness who breathes out lies,
and one who sows discord among brothers.
Proverbs 6:12-19 (ESV)
Hatred stirs up dissension, but love covers over all wrongs.
Proverbs 10:12 (NIV)
A hot-tempered man stirs up strife, but he who is slow to anger quiets contention.
Proverbs 15:18 (ESV)
An arrogant man stirs up strife, but he who trusts in the LORD will prosper.
Proverbs 28:25 (NASB)
The night is nearly over; the day is almost here. So let us put aside the deeds of darkness and put on the armor of light. Let us behave decently, as in the daytime, not in orgies and drunkenness, not in sexual immorality and debauchery, not in dissension and jealousy. Rather, clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the sinful nature.
Romans 13:12-14 (NIV)
I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace.
Ephesians 4:1-3 (ESV)
When you follow the desires of your sinful nature, the results are very clear: sexual immorality, impurity, lustful pleasures, idolatry, sorcery, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, division, envy, drunkenness, wild parties, and other sins like these. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God.
Galatians 5:19-21 (NLT)
Now I urge you, brothers, in the name of our Lord Jesus Christ, that you all say the same thing, that there be no divisions among you, and that you be united with the same understanding and the same conviction.
1 Corinthians 1:10 (HCSB)
Is there any encouragement from belonging to Christ? Any comfort from his love? Any fellowship together in the Spirit? Are your hearts tender and compassionate? Then make me truly happy by agreeing wholeheartedly with each other, loving one another, and working together with one mind and purpose.
Philippians 2:1-2 (NLT)
