Matthew 15:10-20
There are two striking sayings of the Lord Jesus in this passage. One respects false doctrines, the other respects the human heart. Both of them deserve the closest attention.
Respecting false doctrine, our Lord declares, that it is a duty to oppose it, that its final destruction is sure, and that its teachers ought to be forsaken. He says, “Every plant that my heavenly Father has not planted shall be rooted up. Let them alone.”
