“When a poor soul is somewhat awakened by the terrors of the Lord, then the poor creature, being born under the covenant of works, flies directly to a covenant of works again. And as Adam and Eve hid themselves… and sewed fig leaves… so the poor sinner, when awakened, flies to his duties and to his performances, to hide himself from God, and goes to patch up a righteousness of his own. Says he, I will be mighty good now–I will reform–I will do all I can; and then certainly Jesus Christ will have mercy on me.”

(George Whitefield, 1741, Glasgow)

How glorious! Today I am, by the exceeding grace of God, enabled to preach the unsearchable riches of Christ! 
Titus 3:5ff. ‘not by works of righteousness which we have done, but according to His mercy He saved us…through Jesus Christ our Saviour [we are] justified by His grace…’
