Let us muse again today from Matthew 15:9 and the theme of Jesus the king. In our text today our Lord offers a rebuke for the teaching of man’s doctrines. In fact He tells them if you teach what you think, feel, or tradition taught, you worship me in vain. The word vain is the word for a vapor that appears for a moment and then vanishes away. This is another argument for preaching the Bible expositional , line upon line. When we take each word and give its meaning from the ancient languages in its context we get more the mind of God and less of the doctrines of man.
