"Therefore know that only those who are of the faith are sons of Abraham." Galatians 3:7Through Abraham, God showed the world how to practice a faith that is living, objective and brings results. The faith of being obedient or obedience by faith. It is beyond words, it is an act. God doesn't require anything beyond what we are able to offer Him. Everything He asked, Abraham obeyed. This is why He considered him righteous.
