At this time the rite of circumcision was given to Abraham as “a seal of the righteousness of the faith which he had yet being uncircumcised.” Romans 4:11. It was to be observed by the patriarch and his descendants as a token that they were devoted to the service of God and thus separated from idolaters, and that God accepted them as His peculiar treasure. By this rite they were pledged to fulfill, on their part, the conditions of the covenant made with Abraham. They were not to contract marriages with the heathen; for by so doing they would lose their reverence for God and His holy law; they would be tempted to engage in the sinful practices of other nations, and would be seduced into idolatry.

God conferred great honor upon Abraham. Angels of heaven walked and talked with him as friend with friend. When judgments were about to be visited upon Sodom, the fact was not hidden from him, and he became an intercessor with God for sinners. His interview with the angels presents also a beautiful example of hospitality. (PP 138.2) MC VC

In the hot summer noontide the patriarch was sitting in his tent door, looking out over the quiet landscape, when he saw in the distance three travelers approaching. Before reaching his tent, the strangers halted, as if consulting as to their course. Without waiting for them to solicit favors, Abraham rose quickly, and as they were apparently turning in another direction, he hastened after them, and with the utmost courtesy urged them to honor him by tarrying for refreshment. With his own hands he brought water that they might wash the dust of travel from their feet. He himself selected their food, and while they were at rest under the cooling shade, an entertainment was made ready, and he stood respectfully beside them while they partook of his hospitality. This act of courtesy God regarded of sufficient importance to record in His word; and a thousand years later it was referred to by an inspired apostle: “Be not forgetful to entertain strangers: for thereby some have entertained angels unawares.” Hebrews 13:2.

Abraham had seen in his guests only three tired wayfarers, little thinking that among them was One whom he might worship without sin. But the true character of the heavenly messengers was now revealed. Though they were on their way as ministers of wrath, yet to Abraham, the man of faith, they spoke first of blessings. Though God is strict to mark iniquity and to punish transgression, He takes no delight in vengeance. The work of destruction is a “strange work” to Him who is infinite in love. (PP 138.4) MC VC

In the twilight two strangers drew near to the city gate. They were apparently travelers coming in to tarry for the night. None could discern in those humble wayfarers the mighty heralds of divine judgment, and little dreamed the gay, careless multitude that in their treatment of these heavenly messengers that very night they would reach the climax of the guilt which doomed their proud city. But there was one man who manifested kindly attention toward the strangers and invited them to his home. Lot did not know their true character, but politeness and hospitality were habitual with him; they were a part of his religion—lessons that he had learned from the example of Abraham. Had he not cultivated a spirit of courtesy, he might have been left to perish with the rest of Sodom. Many a household, in closing its doors against a stranger, has shut out God’s messenger, who would have brought blessing and hope and peace. (PP 158.1) MC VC

Every act of life, however small, has its bearing for good or for evil. Faithfulness or neglect in what are apparently the smallest duties may open the door for life’s richest blessings or its greatest calamities. It is little things that test the character. It is the unpretending acts of daily self-denial, performed with a cheerful, willing heart, that God smiles upon. We are not to live for self, but for others. And it is only by self-forgetfulness, by cherishing a loving, helpful spirit, that we can make our life a blessing. The little attentions, the small, simple courtesies, go far to make up the sum of life’s happiness, and the neglect of these constitutes no small share of human wretchedness. (PP 158.2) MC VC

Seeing the abuse to which strangers were exposed in Sodom, Lot made it one of his duties to guard them at their entrance, by offering them entertainment at his own house. He was sitting at the gate as the travelers approached, and upon observing them, he rose from his place to meet them, and bowing courteously, said, “Behold now, my lords, turn in, I pray you, into your servant’s house, and tarry all night.” Genesis 19. They seemed to decline his hospitality, saying, “Nay; but we will abide in the street.”(Genesis 19:2) Their object in this answer was twofold—to test the sincerity of Lot and also to appear ignorant of the character of the men of Sodom, as if they supposed it safe to remain in the street at night. Their answer made Lot the more determined not to leave them to the mercy of the rabble. He pressed his invitation until they yielded, and accompanied him to his house. (PP 158.3) MC VC
