If ye be Christ's, then are ye Abraham's seed, and heirs according to the promise. Galatians 3:29. AG 56.1
Of Abraham it is written that “he was called the friend of God,” “the father of all them that believe.” ... AG 56.2
It was a high honor to which Abraham was called, that of being the father of the people who for centuries were the guardians and preservers of the truth of God for the world—of that people through whom all the nations of the earth should be blessed in the advent of the promised Messiah.37Patriarchs and Prophets, 140, 141. AG 56.3
Abraham was honored by the surrounding nations as a mighty prince and a wise and able chief. He did not shut away his influence from his neighbors. His life and character, in their marked contrast with those of the worshipers of idols, exerted a telling influence in favor of the true faith. His allegiance to God was unswerving, while his affability and benevolence inspired confidence and friendship, and his unaffected greatness commanded respect and honor. AG 56.4
His religion was not held as a precious treasure to be jealously guarded and enjoyed solely by the possessor. True religion cannot be thus held; for such a spirit is contrary to the principles of the gospel. While Christ is dwelling in the heart, it is impossible to conceal the light of His presence, or for that light to grow dim. On the contrary, it will grow brighter and brighter as day by day the mists of selfishness and sin that envelop the soul are dispelled by the bright beams of the Sun of Righteousness. AG 56.5
The people of God are His representatives upon the earth, and He intends that they shall be lights in the moral darkness of this world. Scattered all over the country, in the towns, cities, and villages, they are God's witnesses, the channels through which He will communicate to an unbelieving world the knowledge of His will and the wonders of His grace. It is His plan that all who are partakers of the great salvation shall be missionaries for Him. The piety of the Christian constitutes the standard by which worldlings judge the gospel. Trials patiently borne, blessings gratefully received, meekness, kindness, mercy, and love, habitually exhibited, are the lights that shine forth in the character before the world.38Patriarchs and Prophets, 133, 134.
