This advice is from Sunday school -优秀是训练出来的 (5)- on 2/3/19 at Michiana Chinese Christian Church (MCCC). I did not attend this class completely, this post is mainly reconstructed from the handout.
Bible verses:Proverbs 26:4-5 4 Don’t answer a fool according to his folly, lest you also be like him. 5 Answer a fool according to his folly, lest he be wise in his own eyes.
Proverbs 26:12 12 Do you see a man wise in his own eyes? There is more hope for a fool than for him.
