“So understand that it is the people who live by faith [with confidence in the power and goodness of God] who are [the true] sons of Abraham.”
Abraham made a covenant with God that changed his present life and his future generations. He fulfilled his desires and dreams and gave him promises of power!
The Bible says we are descendants of Abraham; we have inherited those blessings. Making us strong in the spirit and in the natural.
We are greatly blessed that God has called us to salvation, but a salvation that comes with a complete package.
We can live life knowing we have the power to receive what we ask for and more - big and unlimited.
