The Religion of Abraham

Jews, Christians and Muslims all claim to follow the God of Abraham. I searched the scriptures to see what Abraham actually believed. This is what I found:

"1 Now the Lord had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed." (Genesis 12)

Clearly, Abraham believed in a God that could talk to him, and give him instructions.

7 And the Lord appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto the Lord, who appeared unto him. (Genesis 12)

Abraham believed in a God that he could see, and that made promises to him.

18 And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.
19 And he blessed him, and said, Blessed be Abram of the most high God, possessor of heaven and earth:
20 And blessed be the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all. (Genesis 14)

Abraham believed his God to be the highest God, whose domain included the stars in the heavens and the earth.

1 And when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect. (Genesis 17)

Abraham was called to represent God, and commanded to be perfect; God is a god of righteousness and works through delegation.

2 And I will make my covenant between me and thee, and will multiply thee exceedingly.
...
7 And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. (Genesis 17)

The God of Abraham makes covenants with people. A covenant is a binding contract that is entered into by two or more parties.

19 For I know him, that he will command his children and his household after him, and they shall keep the way of the Lord, to do justice and judgment; that the Lord may bring upon Abraham that which he hath spoken of him. (Genesis 18)

The covenant which Abraham and his children make with God is to keep his judgements or commandments, and to be just.

It is clear from these scriptures that Abraham believed in a living God who appeared to men, called prophets to represent him, and made covenants with those prophets and those who would follow them. It is also clear that God expected those who covenanted with him to live righteous lives, and keep his commandments. These are the basic tenants of the Abrahamic belief in God.

The question now remains; which modern religions still believe in these tenants?
