Do you remember the time Abraham was willing to sacrifice his son, but God prevented him from dying and promised that he would be a great nation?
No, not Isaac. I’m talking about Ishmael.
Abraham knew sending Isaac and Hagar out meant their death, but God spared them.
Now Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking Isaac. Therefore she said to Abraham, “Drive out this slave woman and her son, for the son of this slave woman shall not be an heir with my son Isaac!” The matter distressed Abraham greatly because of his son Ishmael.
Genesis 21:9-11 (NASB)But God said to Abraham, “Do not be distressed because of the boy and your slave woman; whatever Sarah tells you, listen to her, for through Isaac your descendants shall be named. And of the son of the slave woman I will make a nation also, because he is your descendant.”
Genesis 21:12-13 (NASB)
