Issac's wife was unable to have children and the Lord answered his prayer with twins - Genesis 25:21
In those days, a married couple without children for a long period of time was considered to have shameful lot
Would he give up? Would he father a child with another woman? Would a child come when they were old?
His heart was set on something and he got on his knees and prayed
God delivered not only once but twice
It took 20 years but Issac recived God's blessing in God's way
