"We may see what must be the only ground of our confidence before God.
"It is not our own works of righteousness, nothing wrought in us, or done by us. Neither faith, repentance, nor new obedience. It is Christ's surety-righteousness, nothing without, nothing beside it, It and it only. What he did in satisfaction of law and justice, that only can be a poor sinner's confidence, when standing at the divine tribunal: nothing else can be sustained there. Every other thing, however fair, firm or bulky in the carnal eye, is but unstable water, or yielding air, and shall leave the unhappy man who leans upon it, under an eternal disappointment. Being originally under a covenant of works, a broken covenant, nothing but what was done by Christ to fulfil its precept, and to satisfy its penalty, can be sustained as the ground of our confidence before God. To think any less sufficient, would be saying that sinners can be justified to the prejudice of the covenant of works; that divine justice has abated its demands, and can be pleased without an adequate satisfaction. Be wise, therefore, sinners, be instructed, as ye value your salvation. Trust not in yourselves, in your own hearts, or your own works. Turn away your eyes from everything, in point of confidence, but Christ, and his surety-righteousness."Thomas Bell. A Treatise on the Covenants of Works and Grace, 225
