How was Abraham (the Jewish forefather) saved?
The Bible says he believed God! He believed the promise God gave him. And then, righteousness was imputed to his account. The fact that Abraham was declared righteous before God through his faith was not just for him alone. We read in Romans 3:21-22, that a man is declared righteous through his faith in Jesus Christ. The Bible declares that because of the payment Christ made on the Cross when He shed His blood for our sin, righteousness (right standing) will be imputed to any person’s account who simply believe upon Christ and obeys what He commands.
