Lukas 12:5

Fear Him . . . Fear Him--how striking the repetition here! Only the one fear would effectually expel the other. after he hath killed, &c.--Learn here--(1) To play false with one's convictions to save one's life, may fail of its end after all, for God can inflict a violent death in some other and equally formidable way. (2) There is a hell, it seems, for the body as well as the soul; consequently, sufferings adapted to the one as well as the other. (3) Fear of hell is a divinely authorized and needed motive of action even to Christ's "friends." (4) As Christ's meekness and gentleness were not compromised by such harsh notes as these, so those servants of Christ lack their Master's spirit who soften down all such language to please ears "polite." (See on Mar 9:43-48).

In this chapter we have divers excellent discourses of our Saviour's upon various occasions, many of which are to the same purport with what we had in Matthew upon other the like occasions; for we may suppose that our Lord Jesus preached the same doctrines, and pressed the same duties, at several times, in several companies, and that one of the evangelists took them as he delivered them at one time and another at another time; and we need thus to have precept upon precept, line upon line. Here, I. Christ warns his disciples to take heed of hypocrisy, and of cowardice in professing Christianity and preaching the gospel (Luk 12:1-12). II. He gives a caution against covetousness, upon occasion of a covetous motion made to him, and illustrates that caution by a parable of a rich man suddenly cut off by death in the midst of his worldly projects and hopes (Luk 12:13-21). III. He encourages his disciples to cast all their care upon God, and to live easy in a dependence upon his providence, and exhorts them to make religion their main business (Luk 12:22-34). IV. He stirs them up to watchfulness for their Master's coming, from the consideration of the reward of those who are then found faithful, and the punishment of those who are found unfaithful (Luk 12:35-48). V. He bids them expect trouble and persecution (Luk 12:49-53). VI. He warns the people to observe and improve the day of their opportunities and to make their peace with God in time (Luk 12:54-59).

12:5 hell (Greek Gehenna): The Valley of Hinnom was a ravine along the southwestern side of Jerusalem. It became a metaphor for hell because Israelites had offered their children as sacrifices there (Jer 32:35) and later used it as a place to burn garbage (Jer 19:2, 10-13). Jesus’ disciples should never be afraid of enemies who can only take away their life on earth. Instead, they should fear God, who can give eternal punishment.
