One of the women I am doing my best to learn from is Sarai, Abraham's wife (later to be known as Sarah). For whatever reason, the Lord made it impossible for her to get pregnant. She and Abram lived their married life without conceiving. And she got tired of waiting on the Lord, so sent her servant Hagar to conceive with Abram so that they could have a son to carry on their family. Now, this isn't really the typical way things happen these days, but much can be learned from this situation. Because in the end, Hagar was resentful toward Sarai and no one was really happy with what happened. It was just bad news. Eventually Hagar and her son even got sent into the desert... but that is more to the story you can read in Genesis!
So what is my point here? Sometimes we get tired of waiting on the Lord and don't understand what the heck He is doing, so we try to take matters into our own hands. I am guilty of doing this
