The good person out of the good treasure of his heart brings forth what is good; and the evil person out of the evil treasure brings forth what is evil; for his mouth speaks from that which fills his heart.
Now I urge you, brothers and sisters, keep your eye on those who cause dissensions and hindrances contrary to the teaching which you learned, and turn away from them.
Not returning evil for evil or insult for insult, but giving a blessing instead; for you were called for the very purpose that you would inherit a blessing.
For, “The one who desires life, to love and see good days, Must keep his tongue from evil and his lips from speaking deceit. He must turn away from evil and do good; He must seek peace and pursue it.”
“Do not be like your fathers, to whom the former prophets proclaimed, saying, ‘This is what the Lord of armies says: “Return now from your evil ways and from your evil deeds.” ’ But they did not listen or pay attention to Me,” declares the Lord.
Be strong and courageous, do not be afraid or in dread of them, for the Lord your God is the One who is going with you. He will not desert you or abandon you.
Whatever you do, do your work heartily, as for the Lord and not for people, knowing that it is from the Lord that you will receive the reward of the inheritance. It is the Lord Christ whom you serve.
