The story of Hagar and Sarah is a picture of two totally different approaches to love and fulfilment. Hagar, the servant girl, was used by Abraham to produce a child. Sarah, Abraham’s wife, agreed because she could not bear children. However, although the child Ishmael grew up in Abraham’s household, he would not be the heir. God had promised to give Abraham a son … he had no reason or right to sleep with the servant girl. When God’s promise was finally fulfilled, it became obvious that He was right after all.
