This is fully expressed in that typical representation of
our justification before the Lord, Zech. iii.
3–5. Two things are there expressed to belong to our free
acceptation before God:— 1. The taking away of the guilt of our sin, our
filthy robes; this is done by the death of Christ. Remission of sin is the
proper fruit thereof; but there is more also required, even a collation of
righteousness, and thereby a right to life eternal. This is here called
“Change of raiment;” so the Holy Ghost expresses it again, Isa. lxi. 10, where he calls it
plainly “The garments of salvation,” and “The robe of righteousness.” Now
this is only made ours by the obedience of Christ, as the other by his
death.
