Justification is an act in God, , and imputation of righteousness, should not be considered as the birth of time, but is eternal, because all His immanent acts are so. Is actual Justification the same with personal, and cannot persons be justified before they exist? Then they cannot be personally elected, before their actual existence. If there is a personal election from eternity, there also may be a personal Justification from eternity.

If by actual Justification, or the application of that benefit, when realized by God's elect, for their consolation and joy, it certainly follows faith; and is that Justification by faith which the Scripture speaks of, when faith is taken in a proper sense, but is no evidence that Justification itself is not eternal.

There never was a sinner half as big as Christ is as a Savior.
