More family conflict. More children being born in a weird arms race. And more of the classic family tactic that has only ever made things worse - 'having children' by your servant. It is only getting worse. What is God going to do? Idolatry has snowballed out of control in this family, how is God going to intervene?
Just as He always does, with grace. God remembered Rachel. He had never forgotten, but he works to his own timescale.
The idolatry, sin and conflict does not put God off Rachel. I might have had enough and start withholding affection, but God has not reached that point with me. I have not exhausted his grace.
