Genesis 11:30 says of Abram’s wife, “But Sarai was barren; she had no child.” In Genesis 12 God told Abram to leave his country, family, and his fathers house. He would take him to a new land, make his name great, and bless him.
Verse 3 says, “…and in you all the families of the earth shall be blessed.” Abram was 75. They came to the land of Canaan. Verse 7 says, “…To your descendants I will give this land. And there he built an altar to the Lord, who appeared to him.”
There was a famine in the land and Abram went down to Egypt. Forgetting God’s promise in the face of fear, he asked his wife to lie. In Verse 12 he stated his assumption that they would take her and kill him.
His life was NOT in jeopardy. He was going to be, according to verse 2, a great nation. You and I (Gentiles) would be blessed because of his faith (all families). The Pharaoh treated him well for his wife’s sake. He gave him (verse 16) sheep, oxen, male donkeys, male and female servants, female donkeys, and camels.
When we forget God’s promises, we react in self-preservation. We rely on our flesh, which according to John 6:63 profits nothing. Jeremiah 17:5 says, “…Cursed is the man who trusts in man and makes flesh his strength, whose heart departs from the Lord.”
Note: when God appeared and spoke to Abram he built an altar. He worshipped the Lord. Each time the Lord met him in his journey, he built an altar. The Lord blessed him abundantly. So much so that the land could not hold all that he and his nephew Lot had.
Strife came between Abram and Lot, and their herdsman. Genesis 13:8 says, “So Abram said to Lot, Please let there be no strife between you and me, and between my herdsmen and your herdsmen; for we are brethren.”
Abram gave Lot first choice of what part of the land he wanted. Lot chose Sodom. The Lord appeared to Abram again and added to His earlier promises. Verse 15-16 says, “For all the land which you see I give to you and your descendants forever. And I will make your descendants as the dust of the earth…” In verse 18 Abram built another altar.
