What does it mean for children to obey their parents?
We know we should teach obedience, but in what ways does this apply? What does Scripture say about our obedience to our parents?
Scripture repeatedly underscores and expands the Fifth Commandment principle, teaching us that honoring our parents involves obeying them (Deuteronomy 21:18-21; Ephesians 6:1); honoring them with our words (Exodus 21:17; Leviticus 20:9; Proverbs 20:20; 30:11); showing them respect in every way (Leviticus 19:3), even with our facial expressions (Proverbs 30:17); hearkening to their council (Proverbs 23:22-25); and not treating them lightly in any sense (Deuteronomy 27:16; Ezekiel 22:7). A child's duty to honor parents does not cease even when the child becomes an adult. The inviolability of this law was affirmed by Jesus Himself, who condemned the Pharisees for inventing a way for grownups to circumvent the Fifth Commandment ... (Mark 7:9-13).
