That precious jewel Christ Jesus
Faith, if it is to be sure and steadfast, must lay hold upon nothing else but Christ alone, and in the conflict and terrors of conscience it has nothing else to lean on but this precious pearl Christ Jesus. So, he who apprehends Christ by faith, although he be terrified with the law and oppressed with the weight of his sins, yet he may be bold to glory that he is righteous. How? Even by that precious jewel Christ Jesus, whom he possesses by faith.
