Although the New Testament does not have the book-equivalent of the Old Testament book of Proverbs, there are many passages that could well have been a New Testament chapter in the book of Proverbs.

Romans 12 is one of those chapters. Consider Romans 12:9-21 and start thinking about what the applications to your faith, marriage, home, church, school, workplace, and community can be. You will find it very similar in application to almost any chapter in Proverbs.

Let love be genuine.
Abhor what is evil; hold fast to what is good.
Love one another with brotherly affection.
Outdo one another in showing honor.
Do not be slothful in zeal, be fervent in spirit, serve the Lord.
Rejoice in hope, be patient in tribulation, be constant in prayer.
Contribute to the needs of the saints and seek to show hospitality.
Bless those who persecute you; bless and do not curse them.
Rejoice with those who rejoice, weep with those who weep.
Live in harmony with one another.
Do not be haughty, but associate with the lowly.
Never be wise in your own sight.
Repay no one evil for evil, but give thought to do what is honorable in the sight of all.
If possible, so far as it depends on you, live peaceably with all.
Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.”
Do not be overcome by evil, but overcome evil with good.
