Not Faith, But Christ

Without worthiness in itself, it knits us to the infinite worthiness of Him
in whom the Father delights; and so knitting us, presents us perfect in the
perfection of another. Though it is not the foundation laid in Zion, it brings
us to that foundation, and keeps us there, “grounded and settled” (Col 1:23),
that we may not be moved away from the hope of the gospel. Though it is not
“the gospel,” the “glad tidings,” it receives these good news as God’s eternal
verities, and bids the soul rejoice in them; though it is not the burnt-offering,
it stands still and gazes on the ascending flame, which assures us that the
wrath which should have consumed the sinner has fallen upon the Substitute.

Though faith is not “the righteousness,” it is the tie between it and us. It
realizes our present standing before God in the excellency of His own Son;
and it tells us that our eternal standing, in the ages to come, is in the same
excellency, and depends on the perpetuity of that righteousness which can never
change. For never shall we put off that Christ whom we put on when we believed
(Rom 12:14; Gal 3:27). This divine raiment is “to everlasting.” It waxes not
old, it cannot be rent, and its beauty fadeth not away.
