Matthew 5:46-48

46For if you love [only] those who love you, what reward do you have? Do not even the tax collectors do that?

47And if you greet only your brothers [wishing them God’s blessing and peace], what more [than others] are you doing? Do not even the Gentiles [who do not know the Lord] do that?

48You, therefore, will be perfect [growing into spiritual maturity both in mind and character, actively integrating godly values into your daily life], as your heavenly Father is perfect.
