Matthew 5:45-48

that you may be sons of your Father who is in heaven. For He makes His sun rise on the evil and on the good and sends rain on the just and on the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet your brothers only, what are you doing more than others? Do not even the tax collectors do so? Therefore be perfect, even as your Father who is in heaven is perfect.
