“When sinners are convinced that no blood can expiate their sins but blood of infinite value, and that no obedience can merit eternal life for them but obedience that is infinitely perfect, the Spirit, shining into their darkened understandings and shining at the same time upon the gospel report concerning Christ, discovers to their hearts the excellence and suitableness of His surety-righteousness revealed in the gospel”.
Ibid, p.97
