1 Corinthians 14:20 Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults.
What do you do when someone tells you to grow up or even if they say you acting like an old person? Depending on what it is about it could be a compliment or a rebuke.
Sometimes we do need to stop acting like children and take responsibility for what we do and say; that is when people tell us to grow up. That is the responsibility and respectful position Christ wants us to have.
And other times we have to go back to the innocence that little children display, that innocence that Christ wants us to display because it shows no evil.
