Mateus 5

43 You heard that it was said: You will love your neighbor, and will hate your enemy; 44 but I say to you, love your enemies, bless those cursing you, do good to those hating you, and pray for those accusing you falsely, and persecuting you, 45 that you may be sons of your Father in the heavens, because He causes His sun to rise on evil and good, and He sends rain on righteous and unrighteous. 46 For if you may love those loving you, what reward do you have? Do the tax collectors not also do the same? 47 And if you may greet your brothers only, what do you do abundant? Do the nations not also do so? 48 You will therefore be perfect, as your Father who [is] in the heavens is perfect."
