Matthew 5:46-48

For if you love [only]those who love you, what reward do you have? Do not even the tax collectors do that? And 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? You, 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. [Lev 19:2]
