And why do you look at the speck in your brother's eye, but do not perceive the plank in your own eye? Or how can you say to your brother, 'Brother, let me remove the speck that is in your eye,' when you yourself do not see the plank that is in your own eye? Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck that is in your brother's eye. Luke 6:41-42
As I've grown in grace, I've come to perceive more clearly that the planks in my own eyes are overcome and removed by nothing less than the sufficient grace and love of God working in and through me by the Life of Jesus. As I experience this more and more, I truly do see more clearly how the whole speck-removal thing works in the lives of others.
(BTW, "Plankeye" is the name of a Christian band... I like it so thought I'd use it as the title of this post). =)
