Abraham, Genesis 22 and James 2; Justification before God or men?!

How is the event in Genesis Chapter 22 linked with James Chapter 2 and justification before God or men?
“Abraham saith unto him, They have Moses and the prophets; let them hear them. And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent. And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.” (Luke 16:29 to 31)
