God Promised Abraham And Sarah A Son

God promised to give Abraham a son through his wife Sarah who was barren (unable to bear children). Through this son, a mighty nation would arise and also an uncountable amount of descendants, and one of those descendants would be a blessing to all the nations in the world. This promise seemed impossible because they were so old but Abraham believed what God said, though later he doubted and tried to force God`s hand by having a son through Sarah`s servant girl, Hagar. In ancient times this was accepted, but not in God`s sight. It violated His law for marriage (Gen 2), and Abraham suffered greatly for his sin.
