Recently I came across a web site called, “Lies Moms Tell Their Kids To Get Them To Behave.” One mom was so tired of her kids misbehaving while shopping that she told them the store’s security cameras were actually Santa-cams that had a direct feed to the North Pole, and if they misbehaved, Santa would know.
Of course, Paul gives a different reason why children should obey their parents, saying,
“Children, obey your parents in the Lord: for this is right” (Ephesians 6:1).
This verse is positively sublime in its splendor and simplicity, for it supplies parents with the answer to the eternal question of “why?” You tell your son to do something, and he asks, “Why?” Instead of replying with the usual, “Because I said so,” next time try, “Because God’s Word says that obeying me is the right thing to do!” That’s also a much better reason to ask children to behave than to win the favor of some mythical North Pole elf!
But children are not the only ones whom God calls upon to behave. Paul told Titus,
“But speak thou the things which become sound doctrine: That the aged men be sober, grave, temperate, sound in faith, in charity, in patience” (Titus 2:1,2).
Did you notice that Paul didn’t just tell aged men how to behave, he told them why their behavior should honor the Savior? He pointed out that the things he mentions here are “the things which become sound doctrine.” That word “become” means to make something look good, and making sound doctrine look good is something that all Christians should aspire to do! source
