There is no room for a “way-to-go-you’re-really-trying-hard” speech. Jesus doesn’t give them an “A” for effort. He clearly, boldly, and bluntly says that it is all wrong. There is a right worship and there is a wrong worship that much is clear. God does not simply accept any attempt so long as it “is sincere”.
It is often difficult for Christians today to choose between that which is “good” and that which is “the best.” In this text, we find two women, Mary and Martha—they were sisters of Lazarus and friends of Jesus. Here is Martha busying herself with much serving after having welcomed Jesus into her house.
