Four short commands open the passage, plural and spoken to a whole crowd, each built on one shape. 37"Judge not, and you will not be judged; condemn not, and you will not be condemned." Jesus adds that whatever measure a person uses on others will be used on him, pressed down, shaken together, running over. This is a warning that the posture we take toward people has a way of becoming the posture that meets us.
Then comes an image that is almost comic, and Jesus means it to be: a man with a whole log in his own eye offering delicate surgery on the speck in someone else's. 42"You hypocrite, first take the log out of your own eye, and then you will see clearly." The demand is for clear sight first, so that help becomes possible. A man who cannot see past the timber in his own eye has no business claiming he can fix another's.
The picture shifts from eyes to trees, and the logic tightens. 44"each tree is known by its own fruit." A tree cannot fake its fruit for long. 45"out of the abundance of the heart his mouth speaks." What fills the heart eventually comes out, unbidden, the way water finds its level. Judging others well and living well both come down to the same source, what has taken root inside, in place of what gets performed on the surface.
All of it gathers into the question that gives the passage its edge. 46"Why do you call me 'Lord, Lord,' and not do what I tell you?" Calling Jesus Lord costs nothing. It needs no change of direction and no inconvenience, only the right word at the right moment. Doing what he says is a different matter, and Jesus draws the line with a story about two builders.
48"he is like a man building a house, who dug deep and laid the foundation on the rock." That labor was invisible and unglamorous, likely slower and more expensive than the alternative. The other man built 49"on the ground without a foundation," probably faster and easier. On the day both houses were finished, they may have looked the same. Isaiah had promised that God would lay a sure foundation stone in Zion (Isaiah 28:16), and Jesus reaches for that image, claiming for his own words the ground Isaiah promised.
The difference shows only when the water rises. 48"the stream broke against that house and could not shake it." The other house 49"immediately it fell, and the ruin of that house was great." Every person in the crowd that day heard the same sermon. Hearing was never the test. What separated the houses was whether the words became digging, whether they went down far enough to hold.
Ask what in your life you have heard from Jesus many times and still have not done. That is where the digging is waiting.
Prayer
Father, thank you for words meant to be built upon. Forgive us for the log we missed in our own eye while reaching for the speck in another's, and for calling Jesus Lord with our mouths while building on ground we never dug into. Let whatever floods come find our foundation sunk in the rock of doing what he has said. In Jesus' name, amen.
