Charles Spurgeon wrote, "My faith rests not upon what I am or shall be or feel or know, but in what Christ is, in what He has done, and in what He is now doing for me. Hallelujah!"
Faith is resting in Christ. We know that we are sinners and Christ died for our sins. We are not trusting in self-righteousness. Faith is resting in the righteousness of Christ alone. He is our righteousness.
Spurgeon taught that faith is "in what Christ is, in what He has done, and in what He is now doing." That's our faith resting in Christ. We are saved "looking unto Jesus the author and finisher of our faith" (Hebrews 12:2).
Faith is resting with confidence and assurance in Christ. It is trusting in Christ and not in ourselves. It is knowing Christ as our Surety (Hebrews 7:22). He is our guarantee of eternal salvation.
You can testify with Spurgeon, "My faith rests not upon what I am or shall be or feel or know, but in what Christ is, in what He has done, and in what He is now doing for me. Hallelujah!"
Yes, faith is resting in Christ alone. Then, we may confess, "I am a sinner for whom Christ died." We are focused upon Christ crucified for our sins. No self-righteousness do we claim. We know by faith, that Christ died for our sins. He is risen from the dead as our living Lord.
