Jesus asserts that unless a person’s righteousness exceeds that of the Pharisees and scribes, they will not enter the kingdom of heaven (Matt 5:20). He is not calling for more obedience, but for a deeper obedience that comes from the heart. He then covers five examples of this deeper obedience (murder, adultery [including divorce], oath-taking, retaliation, and loving your enemies). V 48 then concludes this portion of the Sermon on the Mount with the admonition, “Be perfect, therefore, as your heavenly Father is perfect” (NIV),. This is probably a citation of Leviticus 19:2, which uses “holy” and not “perfect” (Deut 18:13 speaks of being “blameless”).
