This testimony is taken out of Psalms 32:1, and it is well enough accommodated to the occasion, for those two, to remit sin, and to impute righteousness, are inseparable. The one is put here figuratively for the other. They mistake, who take occasion from hence to make justification to consist only in remission of sin: the text will not bear it. The apostle's design is, not hereby to declare the full nature of justification, which he had done before; but only to prove the freedom of it from any respect to works, in the instance of this principal and essential part of it. Remission of sin and the imputation of righteousness differ, as the cause and the effect. Remission of sin presupposeth imputation of righteousness; and he that hath his sins remitted, hath Christ's righteousness first imputed, that so they may be remitted and forgiven to sinners.
