The reality of a dysfunctional family, pretending everything is okay.
It's unfortunate, that in families women or young women don't have the positive male figures to set examples as Uncles, brothers, and father's. Without the fear of being raped, sexually assaulted or abused.
The number of unreported cases of abuse, or sex crimes against women still to this day, are alarming. And still ignored by the mainstream. We as mother's and sisters, and daughters have to educate ourselves on the risk of trusting a broken vessel could cause us to loose ourselves that take advantage of our weaknesses.
Sarah demonstrated faith and obedience while believing God's promises. She left her comfortable and familiar surroundings to launch her journey with God.
