Christ addresses commands 5-10, concerning the treatment of our neighbors. All people be they family or strangers are to be treated with the respect afforded them as the image bearers of God. Should they bring shame upon themselves and daily demonstrate they are far from God, they serve as a reminder we were once as wicked as they. Psalm 58.3 reminds us, “the wicked turn aside from the womb, they go astray as soon as they are born, speaking lies.”
We are to care for those who remain fallen away, even and especially when they are sinning against us, or would be considered our enemies. The command to be perfect is addressed as Christ begins to teach on the practical aspects of living a righteous life before God. Being perfect as the Father is perfect is the result of be found righteous in Christ, not because of anything you or I can do, but because of EVERYTHING Christ as accomplished for us.
