Thank you for the question on Abram following God’s command, “Is it true that Abram left his father’s household and all that he knew in his country to follow the Lord and become Abraham?”
As I read the Biblical text, Abram partially obey the LORD God by leaving his country and traveling as far as Haran. Abram’s father, Terah took his grandson Lot to Haran. It is there they settled until Terah died. Even after Terah’s death, Abram felt responsible as an uncle to protect Lot. Thus they traveled together into the Promised Land. Only after a dispute with Lot, that they separated whereby God confirms his covenant with Abram.
Genesis 11:31-12:8 says this, Terah took his son Abram, his grandson Lot son of Haran, and his daughter-in-law Sarai, the wife of his son Abram, and together they set out from Ur of the Chaldeans to go to Canaan. But when they came to Harran, they settled there.
The LORD had said to Abram, “Go from your country, your people and your father’s household to the land I will show you.2 “I will make you into a great nation and I will bless you; I will make your name great, and you will be a blessing. 3 I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you.” 4 So Abram went, as the LORD had told him; and Lot went with him. Abram was seventy-five years old when he set out from Harran. 5 He took his wife Sarai, his nephew Lot, all the possessions they had accumulated and the people they had acquired in Harran, and they set out for the land of Canaan, and they arrived there (A searchable online Bible in over 150 versions and 50 languages).
Acts 7 says this, “To this he replied: “Brothers and fathers, listen to me! The God of glory appeared to our father Abraham while he was still in Mesopotamia, before he lived in Harran. 3 ‘Leave your country and your people,’ God said, ‘and go to the land I will show you.’’ 4 “So he left the land of the Chaldeans and settled in Harran. After the death of his father, God sent him to this land where you are now living” (NIV).
It may well be that Abram could not abandon his father in Ur of Chaldea. They left together Ur and traveled to Haran to settle down. He may have wanted to wait until his father die before he traveled to the Promised Land in obedience to Promise given to him by the LORD God.
SUMMARY: Abram partially obey the LORD God by following his father Terah and taking Lot, his nephew with him.
