Genesis 25
This chapter tells us how Rebekah had sons. She was barren just like her mother in law Sarah. But Jacob entreated God. He asked earnestly. He prayed and begged God to open Rebekah’s womb. Then his wife conceived.
Praying earnestly means to pray with sincere and intense conviction. Whatever you are asking God today. No matter how hard or seems impossible, remember the God who answered the earnest prayer of Isaac is the same God we have today and forever.
