Dr. Luke records Jesus’ Beatitudes from His “Sermon on the Plain” in today’s Bible reading. It’s very similar to Matthew’s version from Jesus’ “Sermon on the Mount”.
Dr. Luke juxtaposes the blessings in verses 20-22 against the judgmental attitude of the Pharisees in verses 1-11, and then his instructions on judging in verses 24-26 and 37-45.
The key verse in the “don’t judge” part of the passage (Luke 6:37-42) is at the end of verse 45:
“A good person produces good out of the good stored up in his heart. An evil person produces evil out of the evil stored up in his heart, for his mouth speaks from the overflow of the heart.” Luke 6:45 (CSB)
The Pharisees’ words only revealed their hypocritical, judgmental hearts. And Jesus warned that when we judge, our judgment will return to back to us … in abundance. (Luke 6:37-38)
Moralism looks good. That’s when you’re doing all the right things and not doing any of the wrong things. It looks really good … on the outside. But the Pharisees’ problem was not their behavior — which was exemplary. Their problem was on the inside: their wicked hearts. And their hearts couldn’t be fixed by their behavior because behavior follows the heart, not the other way around.
Remember, the Christian walk isn’t about behavior change. It’s about a relationship with Jesus Christ. Don’t focus primarily on your behavior. Instead, look at your heart. Ask God to reveal your heart when you’re inclined to judge. Hint: Your heart is darker than you think! (Jeremiah 17:9) Deal with your heart and your behavior will follow.
