And Abraham gave all that he had unto Isaac.
Therefore she said to Abraham, "Drive out this maid and her son, for the son of this maid shall not be an heir with my son Isaac."
The matter distressed Abraham greatly because of his son.
But God said to Abraham, "Do not be distressed because of the lad and your maid; whatever Sarah tells you, listen to her, for through Isaac your descendants shall be named.
"Now Sarah my master's wife bore a son to my master in her old age, and he has given him all that he has.
You have ascended on high, You have led captive [Your] captives; You have received gifts among men, Even [among] the rebellious also, that the LORD God may dwell [there].
"All things have been handed over to Me by My Father; and no one knows the Son except the Father; nor does anyone know the Father except the Son, and anyone to whom the Son wills to reveal [Him].

nor are they all children because they are Abraham's descendants, but: "THROUGH ISAAC YOUR DESCENDANTS WILL BE NAMED."

1 Corinthians 3:21-23
So then let no one boast in men. For all things belong to you,
whether Paul or Apollos or Cephas or the world or life or death or things present or things to come; all things belong to you,
and you belong to Christ; and Christ belongs to God.
And if you belong to Christ, then you are Abraham's descendants, heirs according to promise.
And you brethren, like Isaac, are children of promise.
For it was the [Father's] good pleasure for all the fullness to dwell in Him,
in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
