What is the theme in Eternity in Their Hearts by Don Richardson?

Abraham's Covenant is another theme in the book. According to the Bible, 4,000 years ago, there was a righteous man named Abram. God saw how good Abram was, and decided to make a covenant with Abram. He changed Abram's name to Abraham, which means Father of Many, and tested Abraham's obedience by asking him to sacrifice his son Isaac. When Abraham came very close to doing just that, God stopped him, and made a covenant with him.
