And it is the molecules. Justification carried forward into the present and future by the Resurrection is Easter truth. Luther saw it and passed it on, although the insight faded somewhat over time. Cranmer picked it up and prayed it. The Reformation was born through it.
Forgiveness is only negative, the removal of the condemnation.
Forgiveness is an act, and a succession of isolated acts from time to time. Justification is an act which results in a permanent relation or position in the sight of God. Forgiveness is repeated throughout our life. We are accounted righteous before God, only for the merit of our Lord and Saviour Jesus Christ by Faith, and not for our own works or deservings. Wherefore, that we are justified by Faith only, is a most wholesome Doctrine, and very full of comfort, as more largely is expressed in the Homily of Justification.
