Nobody has ever questioned that the descendants of Abraham inherited the land.
We all know that they are living in Israel today.
But Abraham was promised the land and he never received even one foot of ground.
Genesis 17:8
"I will give to you and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God."
Acts 7:5
"But He gave him no inheritance in it, not even a foot of ground, and yet, even when he had no child, He promised that HE WOULD GIVE IT TO HIM AS A POSSESSION, AND TO HIS DESCENDANTS AFTER HIM.
This is proof positive that Jesus did not fulfill the Law and the Prophets.
Abraham NEVER received what was promised to him.
