Imputed righteousness is a lie. God does not look on Christians through the garb of Christ's blood. True repentance means ceasing from all sin before we die. Salvation is not so dependent on whether we accept Christ - it's whether He will accept us. We need to do more so that He will want to accept us.
Salvation is dependent upon our adherence to moral law.
God is holy only because He chooses to use His attributes in a loving way. God has the ability to make wrong choices or to sin. Our moral character is shaped merely by our individual acts of sin. If an individual unknowingly commits a sin, it is not a sin to that person and they will not be held to account for it by God. The sin of Adam is not transmitted to us, and it would be unjust for God to pronounce us guilty because of his sin.
