The Lord appeared to Abraham near the great trees of Mamre along with two angels as recorded in Genesis 18. Abraham met them and invited them to stay for a while, rest, and have a meal. They agreed so as Sarah was preparing the meal, the conversation turned to Sarah having a child.
Sarah overheard the conversation and laughed at the thought of having a child at such an age (vv. 11-15). She was beyond child bearing age and her laugh was one of disbelief. The Lord heard her laugh and asked why she lacked the faith to believe that all things are possible for the Creator.
The conversation then turned to Sodom. The nephew of Abraham named Lot and his family was among the people in Sodom and Abraham showed concern; hoping the Lord would spare the city if there were a few righteous people among them.
Abraham was interceding for any righteous people of Sodom and God was listening to his prayer. We learn that God did consider what Abraham was asking. This day, we can also know that God listens to our prayers. We can ask for direction in what we do and know that one day at a time, the impossible can become possible.
