Therefore He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?— just as Abraham “believed God, and it was accounted to him for righteousness.” Therefore know that only those who are of faith are sons of Abraham.
What made Abataham Jewish? He believed God! Interestingly the Bible says that ONLY those who are of faith are the children of Abraham. Have you got faith? Are you believing God?
