Genesis 16 – Ishmael’s Introduction
So, God has explicitly promised Abraham an heir who is his son by birth. But Sarah has been unable to conceive and is well past child-bearing age. Where is this heir going to come from? Sarah has an idea: God said the heir would come from Abraham, but he didn’t say it had to come from Sarah. Thus, she’ll give her maid Hagar to Abraham, and Hagar and Abraham will have the child. Problem solved, right? No. There are complications.
