You totally made that up. Where do we see that Abraham realized that he or Sarah made a mistake? What passage indicates he was worried about god’s retribution. Where do we see any response from god concerning Sarah’s decision?
What we see is that an angel of god spoke to Hagar and told her to go back and that her son would not be forgotten in the promises given to Abraham and his seed. Basically, Hagar flaunted her position and abused Sarah’s gift of her husband. Abraham told Sarah she could do with the woman as she pleased and so in turn Sarah made Hagar’s life miserable and Hagar left. The angel told Hagar go back and live it. In effect, go back an apologize.
My reasoning is also conjecture because the scriptures don’t actually say that, but I cannot see your story of what happened (guilt, fear) anywhere in the scriptures.
Right, however, God promised Abram and Sarai that they would bear a child in their old age, together. Ten years go bye, and Sarai, not trusting God’s promise, takes matters into her own hands and tells Abram to have intercourse with Hagar. This was Sarai’s actions, not God’s. Abram, Sarai, Hagar and Ishmael then live in the expectation that Ishmael is the child that God promised, which is of course, not true. It is the child that Sarai arranged to come into the world via her own plans and ambitions, of which Abram cooperated with with. But Ishmael was not the fulfillment of God’s promise…
Years later, God makes his covenant with Abram, changing his name to Abraham and his wife’s name to Sarah. Telling them, again, that Sarah will have a son. The shock is throughout the following passages. Abraham’s response indicates he is worried about the fate of Ishmael, who but moments before he believed was the child that would be blessed by God. Now, what is the fate of this child? What can a father do but ask God have favor on this child? How bigger of a thing is it to ask when you KNOW that this child is a product of your lack of faith and trust in God?
Genesis 17
18
So Abraham said to God, “If only Ishmael could live in your favor!”
Why would Abraham worry that Ishmael was not in God’s favor, if he believed something was right about the whole situation?
God then says, again, that Abraham and Sarah will have a child. Which is the promise made, and not believed by Sarah earlier in her life. Where she then contrived to make a promise of God come to pass without God.
19
God replied: Even so, your wife Sarah is to bear you a son, and you shall call him Isaac. It is with him that I will maintain my covenant as an everlasting covenant and with his descendants after him.
God then shows mercy to Abraham and shows that his prayer for Ishmael has not gone unheard:
20
Now as for Ishmael, I will heed you: I hereby bless him. I will make him fertile and will multiply him exceedingly. He will become the father of twelve chieftains, and I will make of him a great nation.
But again, makes it clear that the covenant with Abraham and his descendants will be maintained through Isaac, who is the promised child from God, and not the child that came from Sarah’s unfaithfulness to God.
21
But my covenant I will maintain with Isaac, whom Sarah shall bear to you by this time next year.
Beyond that, Sarai’s choices brought discord into the home. Jealousies and complications to heredity that would not have been there, had Abraham and Sarah trusted God and remained true to each other. Bringing Hagar into the mix solved nothing, and was not the means to make a promise of God come to pass, without God.
Sarai and Abram acted on their own, in an attempt to fulfill a promise of God. “Oh look, Abraham has a child, God’s promise is fulfilled.” NOT! Obviously, this whole extramarital relationship was unnecessary, and was not commanded by God, as evidenced by Isaac.
