Yes, before the fall,  Adam had God’s righteousness on him, and enable him to walk with God without any condemnation. When sin came, he lost all the right to walk with God for he’s guilty of every allegation against him. On the Cross, Jesus restored this righteousness and much more. Reflect on this: “He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed. For you were straying like sheep, but have now returned to the Shepherd and Overseer of your souls.” (1 Peter 2:24-25)
