18:16-22 The two who are supposed to have been created angels went toward Sodom. The one who is called Jehovah throughout the chapter, continued with Abraham, and would not hide from him the thing he intended to do. Though God long forbears with sinners, from which they fancy that the Lord does not see, and does not regard; yet when the day of his wrath comes, he will look toward them. The Lord will give Abraham an opportunity to intercede with him, and shows him the reason of his conduct. Consider, as a very bright part of Abraham's character and example, that he not only prayed with his family, but he was very careful to teach and rule them well. Those who expect family blessings must make conscience of family duty. Abraham did not fill their heads with matters of doubtful dispute; but he taught them to be serious and devout in the worship of God, and to be honest in their dealings with all men. Of how few may such a character be given in our days! How little care is taken by masters of families to ground those under them in the principles of religion! Do we watch from sabbath to sabbath whether they go forward or backward?The promise to Sarah. The men now enter upon the business of their visit. "Where is Sarah thy wife?" The jealousy and seclusion of later times had not yet rendered such an inquiry uncourteous. Sarah is within hearing of the conversation. "I will certainly return unto thee." This is the language of self-determination, and therefore suitable to the sovereign, not to the ambassador. "At the time of life;" literally the living time, seemingly the time of birth, when the child comes to manifest life. "Sarah thy wife shall have a son." Sarah hears this with incredulous surprise, and laughs with mingled doubt and delight. She knows that in the nature of things she is past child-bearing. "Is anything too hard for the Lord?" Sarah laughed within herself, within the tent and behind the speaker; yet to her surprise her internal feelings are known to him. She finds there is One present who rises above the sphere of nature. In her confusion and terror she denies that she laughed. But he who sees what is within, insists that she did laugh, at least in the thought of her heart. There is a beautiful simplicity in the whole scene. Sarah now doubtless received faith and strength to conceive.

Verse 16-33

The conference concerning Sodom. The human manner of the interview is carried out to the end. Abraham convoys his departing guests. The Lord then speaks, apparently debating with himself whether he shall reveal his intentions to Abraham. The reasons for doing so are assigned. First. Abraham shall surely become a nation great and mighty, and therefore has the interest of humanity in this act of retribution on Sodom. All that concerns man concerns him. Second. Blessed in him shall be all the nations of the earth. Hence, he is personally and directly concerned with all the dealings of mercy and judgment among the inhabitants of the earth. Third. "I have known him." The Lord has made himself known to him, has manifested his love to him, has renewed him after his own image; and hence this judgment upon Sodom is to be explained to him, that he may train his household to avoid the sins of this doomed city, "to keep the way of the Lord, to do justice and judgment; and all this to the further intent that the Lord may bring upon Abraham what he hath spoken of him." The awful judgments of the Lord on Sodom, as before on the antediluvian world, are a warning example to all who are spared or hear of them. And those who, notwithstanding these monuments of the divine vengeance, will cease to do justice and judgment, may be certain that they will not continue to enjoy the benefits of the covenant of grace. For all these reasons it is meet that the secret of Lord be with him Psalm 25:11.

17. the Lord said, Shall I hide—The chief stranger, no other than the Lord, disclosed to Abraham the awful doom about to be inflicted on Sodom and the cities of the plain for their enormous wickedness. q.d. Seeing I have done greater things for him, how can I deny him the less? Compare the argument, Romans 8:32. God’s ways are not like men’s ways. Former favours to men are arguments why they should do no more, but to God they are motives for the adding of new ones.

Seeing that Abraham shall surely become a great and mighty nation,.... Which was fulfilled in the nation of Israel, so called, not so much for the largeness of the place they dwelt in, and the number of its inhabitants, as for the law of God that was given them, and the worship of God kept up among them; on account of which there was no nation so great, Deuteronomy 4:8,

and all the nations of the earth shall be blessed in him; in his seed, the Messiah, in whom some of all nations are blessed with all spiritual blessings. Now, since God had promised, and would do such great things for him and his, he judged it right and proper not to hide from him what he was about to do at Sodom, and the rather, as he had a near relation that dwelt there.

Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
