Genesis 16 · a question people ask
Was Sarai and Abram's plan wrong?
The chapter doesn't pass a verdict. It reports the plan (16:2-3) and the pain that follows: contempt, blame, harshness and flight (16:4-6). Protestants read it two ways.
How Christians read it
Where Christians differ, Favor sets out the main views side by side and doesn't pick one.
Taking the promise into their own hands
God had promised an heir from Abram's own body (15:4), and Sarai tries to get one through her servant: "It may be that I will obtain children by her" (16:2). Some who hold this view also point to Paul, who calls Ishmael the son "born according to the flesh" and Isaac the son "born through promise" (Galatians 4:23), though Paul uses the story as an allegory of two covenants (4:24) rather than as a verdict on the plan.

A story told without comment
The text simply reports what happened. God had not yet said the heir would be Sarai's son; that comes later (17:16, 19). And God cares for Hagar and blesses her son (16:10-11).
