God created each woman for a purpose. And for those He has called to be a mother, God desires for them to be "grounded in the Gospel and content in their role." Satan on the other hand wants these women to be discontent and seek their fulfillment outside of God's plan.
Scripture calls mothers to be content, firmly grounded in the conviction that their identity is found, not in being a mother, but in being "beloved of God in the Gospel."
