ABRAHAM: THE FATHER OF NEW COVENANT DISCIPLES
People who have struggled to leave religion and reject all of its rewards because of a vague promise of some unknown, unpredictable future will understand why God uses these terms.

People who act on faith to make such changes in their life show evidence that they are children of Abraham. They exercise faith in God’s promise about the unknown, unpredictable future in a promised land filled with enemies if they willfully choose to give up the religious life they have come to depend on. No one is forcing people to leave religion but faith in the promise drives them to separate from religion and friends and family they will leave behind who are still religious.
