True and Permanent Rest

“On the system of ‘Do this and live,’ no peace, and even no true obedience, can ever be attained. It is ‘Believe on the Lord Jesus Christ and thou shalt be saved.’ When this belief enters the heart, joy and confidence enter along with it. The righteousness we try to work out for ourselves eludes our impotent grasp, and never can a soul arrive at a true and permanent rest in the pursuit of this object.” -- Thomas Chalmers
