Luke 6:40

The disciple, &c.--that is, "The disciple aims to come up to his master, and he thinks himself complete when he does so: if you then be blind leaders of the blind, the perfection of one's training under you will only land him the more certainly in one common ruin with yourselves."

In this chapter we have Christ's exposition of the moral law, which he came not to destroy, but to fulfil, and to fill up, by his gospel. I. Here is a proof of the lawfulness of works of necessity and mercy on the sabbath day, the former in vindication of his disciples' plucking the ears of corn, the latter in vindication of himself healing the withered hand on that day (Luk 6:1-11). II. His retirement for secret prayer (Luk 6:12). III. His calling his twelve apostles (Luk 6:13-16). IV. His curing the multitudes of those under various diseases who made their application to him (Luk 6:17-19). V. The sermon that he preached to his disciples and the multitude, instructing them in their duty both to God and man (v. 20-49).
