Evangelicalism and Christ
In their concern to focus attention on the atoning death of Christ, as the sole sufficient ground on which sinners may be accepted with God, they have expounded the summons to saving faith in these terms: "Believe that Christ died for your sins." The effect of this exposition is to represent the saving work of Christ in the past, dissociated from his Person in the present, ent, as the whole object of our trust. But it is not biblical thus to isolate the work from the Worker. Nowhere in the New Testament is the call to believe expressed in such terms. What the New Testament calls for is faith in (en) or into (eis) or upon (epi) Christ himself-the placing of our trust in the living Savior, who died for sins. The object of saving faith is thus not, strictly speaking, the atonement, but the Lord Jesus Christ, who made atonement. We must not, in presenting the gospel, isolate the cross and its benefits from the Christ whose cross it was. For the persons to whom the benefits of Christ's death belong are just those who trust his Person, and believe not upon his saving death simply, but upon him, the living Savior.
