@Ajax93 Interestingly enough, for me Hagar is a perfect example of the mercy of God on all people by her own testimony. After she was evicted from the household and did not know what to do, the Lord met her and gave her guidance. She then said You are the God who sees me. What a powerful statement! The God who sees us when we are cast off; the God who sees us when no one else does the God who is with all who call upon His name.
Genesis 16:13-14 - She gave this name to the Lord who spoke to her: “You are the God who sees me,” for she said, “I have now seen the One who sees me.” That is why the well was called Beer Lahai Roi; it is still there, between Kadesh and Bered.
Regarding Ishmael, I think he has gotten a bad reputation because of the way he is often contrasted with Isaac, who was the child of God’s promise, and sometimes associated with Islam (a claim that is likely not true regardless). In reality, we see that God blesses Ishmael at Abraham’s request. I am not sure the text gives us enough information to know if Ishmael chose to worship the God of Abraham or the gods of the nations…
Genesis 17:20 - And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation.
Hope that helps
