Raising the Dead: Bonar – The Everlasting Righteousness: Chapter 6
This righteousness is “reckoned” or “imputed” to all who believe; so that they are treated by God as if it were actually theirs. They are entitled to claim all that which such righteousness can merit from God, as the Judge of righteous claims. It does not become ours gradually, or in fragments or drops; but is transferred to us all at once.
