Matthew 7:3-5 NIV
“Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye?  How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye?  You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.”

What do you think? What would be an example of a “plank”? Can you think of an example of a “speck” in someone else’s eye? How does grace fit into this?
(I can think of lots of planks I have had in my own eyes at times – bad attitude, wrong thinking about myself and others, minimizing my sin or God’s grace, wanting blessing for me and cursing for them. And, yes, these words are convicting.) Lord, have mercy on us all.
