My grandson, who has a very high IQ, shared with me that his mother told him to act smart. I’m guessing she wants him to use his words properly so he doesn’t appear uneducated. That was the perfect response to him because kids tend to do and say ignorant things because they are still learning. He’s only 8, but many say they are Christian, using Christ’s name, but continue to act and say things that make them appear worldly, having never turned away from their former self to begin moving toward sanctification. Like my grandson, whose mother told him to act smart, we should do our best to act holy until the day Jesus appears; we will never be completely holy until we are in his presence, but we should do our best to represent him until that day comes.
to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness. Ephesians 4:22-24
