Matthew 5

48 Therefore, you be perfect just as your Father in the heavens is perfect.*"Perfect"—the Father is our point of reference; we are to be like He is. A standard is a standard; it is not invalidated just because we may feel that it is unattainable. Comparing this passage with texts like Deuteronomy 7:10, "He repays those who hate Him to their face", and Psalm 5:5-6, "You hate all workers of iniquity", I take it that we must distinguish between personal enemies (those who oppose us for personal reasons) and enemies of God and His truth. To be like the Father we also must hate workers of iniquity (because of the consequences to others).
