(Proverbs 9:9 KJV) Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
Being “just" (righteous NASB) (6662) makes you teachable. I never thought of that in those terms.
First, the righteous have the humility to know they are ignorant. You might call this a teachable spirit. Believers are always seeking to know more whether it be the science of God’s creation or the intricacies of the government He has given us. Because we know the Eternal we see how small our knowledge really is.
Second, the righteous have the courtesy to listen. That is so simple. We don’t insist on doing all the talking. We accept that others have something to say.
Third, the righteous has the Holy Spirit. One of His roles is to bring to mind the things we need to know in persecution. You can’t bring to mind what isn’t there. I guess He could, but that isn’t the point Jesus was making.
So? You have much to learn today. Every corner you go around will have new knowledge or refresher courses in past lessons. Glory.
