The law reigned and condemned all, but justification happened the same way in the OT. God attributed righteousness to Abraham for his faith.
Genesis 15:6 And he believed in the LORD; and he counted it to him for righteousness.

Hebrews 11:7 By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith.
