As I have homeschooled my children over the last 20 years, they have become very familiar with an object they call “the dreaded red pen”. One of my sons would even start humming the ominous music from Star Wars every time I whipped it out. Each time they took a test or wrote a report, I used the red pen to mark their papers and show them what was wrong and needed correcting. They didn’t always like it, but I would point out that it didn’t do them any favors to let them have wrong answers or papers that weren’t fixed. There would be negative long term consequences if the problems weren’t corrected now. Correction isn’t just needed for school work, but in life. When we as parents see our children doing something that is wrong, correction is necessary to avoid eternal consequences. Correction is not something that only applies to children. Even as adults, there are times that we need to make changes in our lives in order to please our Father in heaven.
In many versions of the Bible today, the words of Jesus are printed in red. Many of these words are teachings and commands that we are to follow. They tell us how we need to live 
our lives in a way that will be pleasing and acceptable to Him. Now some of these teachings are hard – hard enough that they may require some changes on our part.
Generally, there are two reactions to correction: 1) A heart is soft and yielding to the correction and willing to change, or 2) A heart “sees red” and becomes angry and rebellious to changing. One example of this is found in Jeremiah 36 when the words of the Lord were given to Jeremiah the prophet to write down in a scroll and then be read before Jehoiakim, the king of Judah. When the scroll was read in the presence of the king, the word of God so enraged him that he took a knife and cut up the scroll and then cast it into the fire (v. 23). Not liking God’s Word doesn’t change the truth of it. (Incidentally, God had Jeremiah write the same words down in another scroll [v. 27-28]). His truth cannot be destroyed! When we are confronted with the truth of the Bible and we see that opinions or attitudes or behavior needs to change, what is our response? Do we need to “get out the red pen” so to speak and start marking areas of our life that need correction?
Don’t let words of correction cause you or your children to be angry or disheartened, but rather let them teach and encourage you to be the kind of people God wants you to be.
