. . . Resting upon Christ means wholly looking to Him for everything that has to do with our salvation. Genuine faith in Christ does not trust Him to pardon sin and then trust itself to overcome sin. It trusts Christ for both. We must depend upon the Lord to keep us to the end just as we do for pardon from the past. We rejoice in a Savior who promises to keep us as long as we keep ourselves. There must be no reliance for us but upon Christ for all things—-wisdom, righteousness, sanctification, ultimate perfection. We are complete in Christ and can add no perfection to Him.
