Matthew 5:45-49

so that you may prove yourselves to be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.

For if you love those who love you, what reward do you have? Even the tax collectors, do they not do the same?

And if you greet only your brothers and sisters, what more are you doing than others? Even the Gentiles, do they not do the same?

Therefore you shall be perfect, as your heavenly Father is perfect.
