Luke 6:40

Every one that is perfect - Or, thoroughly instructed, κατηρτισμενος: - from καταρτιζω, to adjust, adapt, knit together, restore, or put in joint. The noun is used by the Greek medical writers to signify the reducing a luxated or disjointed limb. It sometimes signifies to repair or mend, and in this sense it is applied to broken nets, Matthew 4:21; Mark 1:19; but in this place, and in Hebrews 13:21; 2 Timothy 3:17, it means complete instruction and information. Every one who is thoroughly instructed in Divine things, who has his heart united to God, whose disordered tempers and passions are purified and restored to harmony and order; every one who has in him the mind that was in Christ, though he cannot be above, yet will be as, his teacher - holy, harmless, undefiled, and separate from sinners.

"The disciple who perfectly understands the rules and sees the example of his master, will think it his business to tread exactly in his steps, to do and suffer upon like occasions, as his master did: and so he will be like his master." Whitby.

The disciple is not ... - The learner is not above his teacher, does not know more, and must expect to fare no better. This seems to have been spoken to show them that they were not to expect that their disciples would go "beyond them" in attainments; that if they were blind, their followers would be also; and that therefore it was important for them to understand fully the doctrines of the gospel, and not to be blind leaders of the blind.

Every one that is perfect - The word rendered "is perfect" means sometimes to repair or mend, and is thus applied to mending nets, Matthew 4:21; Mark 1:19. Hence, it means to repair or amend in a moral sense, or to make whole or complete. Here it means, evidently, "thoroughly instructed" or "informed." The Christian should be like his Master - holy, harmless, and undefiled, and separate from sinners. He should copy his example, and grow into the likeness of his Redeemer. Nor can any other be a Christian.
