To truly believe, there must be a clear conviction of sin, and the merits of the blood of Christ, and of Christ’s willingness to save upon this consideration, merely, that you are a sinner. These things are harder than to make a world. All the power in nature cannot get up so high in a storm of sin and guilt as really to believe there is any grace, any willingness in Christ to save. When Satan charges sin upon the conscience, then for the soul to charge it upon Christ, that is gospel-like; that is to make Him Christ. He serves for that use, to accept Christ’s righteousness alone, His blood alone for salvation, that is the sum of the gospel. When the soul, in all duties and distress, can say, “Nothing but Christ, Christ alone, for righteousness, justification, sanctification, redemption” (I Cor 1:30); not my humblings, not my duties, not my graces; then that soul has got above the reach of the billows.
