Entitled to Use Another's Name

To be entitled to use another's name, when my own name is worthless; to be allowed to wear another's raiment, because my own is torn and filthy; to appear before God in another's person,- the person of the Beloved Son,- this is the summit of all blessing. The sin-bearer and I have exchanged names, robes, and persons! I am now represented by Him, my own personality having disappeared; He now appears in the presence of God for me (Hebrews 9:24). All that makes Him precious and dear to the Father has been transferred to me. His excellency and glory are seen as if they were mine; and I receive the love, and the fellowship, and the glory, as if I had earned them all. So entirely one am I with the sin-bearer, that God treats me not merely as if I had not done the evil that I have done; but as if I had done all the good which I have not done, but which my Substitute has done. In one sense I am still the poor sinner, once under wrath; in another I am altogether righteous, and shall be so for ever, because of the Perfect One, in whose perfection I appear before God. Nor is this a false pretense or a hollow fiction, which carries no results or blessings with it. It is an exchange which has been provided by the Judge, and sanctioned by law; an exchange of which any sinner upon earth may avail himself and be blest.
