He was 75 years old but his name was Abram until he was 99 years old. Genesis 12:1-4 "Now the LORD had said to Abram, Depart from your country, and from your kindred, and from your father's house, to a land that I will show you: (2) And I will make of you a great nation, and I will bless you, and make your name great; and you shall be a blessing: (3) And I will bless them that bless you, and curse him that curses you: and in you shall all families of the earth be blessed. (4) So Abram departed, as the LORD had spoken to him, and Lot went with him: and Abram was seventy and five years old when he departed from Haran." Genesis 17:1-5 "And when Abram was ninety and nine years old, the LORD appeared to Abram, and said to him, I am the Almighty God; walk before me, and be you perfect. (2) And I will make my covenant between me and you, and will multiply you exceedingly. (3) And Abram fell on his face: and God talked with him, saying, (4) As for me, behold, my covenant is with you, and you shall be a father of many nations. (5) Neither shall your name any more be called Abram, but your name shall be Abraham; for a father of many nations have I made you."
God chose Abraham because of God saw Abraham was worthy of a blessing and he had a clean heart.
Abraham
"Here I am."
It is called the "Covenant"-- the promise Abraham made with God, and God made with Abraham.
God called Abraham righteous because of his faith and obedience. Abraham trusted in God's promises, demonstrated by his willingness to leave his homeland and obey God's commands, such as when he was prepared to sacrifice his son Isaac. This faith and obedience showed Abraham's righteousness before God.
God, Abraham and Moses are all still called by their names. Only Jacob's name was changed and he is now called Israel.
The name Abram means "Exalted Father". This was changed during the narrative in the Book of Genesis to Abraham, which means "Father of many". The story describes God as promising Abraham that he would be the father of many nations, and goes on to describing his descendants as founding different nations in the Near East.
In the book of Genesis in the Bible, God promised Abraham and Sarah a son, even in their old age. Abraham was 100 and Sarah was 90 when Isaac was born. The "Child of the Promise" refers to God's promise to Abraham and Sarah.
Abraham lived in Ur first and then Haran before he was called by God. The story can be found in Genesis 11:31.
Abraham chose God before God chose him. Abraham, on his own, had rejected the idols his family and country worshiped and intuitively followed the teachings of the Torah. It's for this reason that he is considered the spiritual forefather of the Jews besides his being their ancestor.
Abraham was the father of the Jewish nation, as well as Islam, he was always obedient to god.
Human, I would imagine. There is only one case in Genesis - where Abraham was called by God to sacrifice his son, Isaac. However, at the moment of slaughter, God called on Abraham to spare his son and slaughter a ram which was now conveniently trapped in a bush nearby. Abraham happily did so.
