_Secondly_, Would Jesus Christ have mercy offered in the first place to the biggest sinners, to the Jerusalem sinners? then, by this also, you must learn to judge of the sufficiency of the merits of Christ; not that the merits of Christ can be comprehended, for that they are beyond the conceptions of the whole world, being called the unsearchable riches of Christ; but yet they may be apprehended to a considerable degree. Now, the way to apprehend them most, is, to consider what offers, after his resurrection, he makes of his grace to sinners; for to be sure he will not offer beyond the virtue of his merits; because, as grace is the cause of his merits, so his merits are the basis and bounds upon and by which his grace stands good, and is let out to sinners.
Doth he then command that his mercy should be offered in the first place to the biggest sinners? It declares, that there is sufficiency in his blood to save the biggest sinners. The blood of Jesus Christ cleanseth from all sin. And again, “Be it known unto you therefore, men and brethren, that through this man (this man’s merits) is preached unto you the forgiveness of sins: and by him all that believe are justified from all things, from which ye could not be justified by the law of Moses;” Acts xiii. 38.
Observe then thy rule to make judgment of the sufficiency of the blessed merits of thy Saviour. If he had not been able to have reconciled the biggest sinners to his Father by his blood, he would not have sent to them, have sent to them in the first place, the doctrine of remission of sins; for remission of sins is through faith in his blood. We are justified freely by the grace of God, through the redemption that is in the blood of Christ. Upon the square, as I may call it, of the worthiness of the blood of Christ, grace acts, and offers forgiveness of sin to men; Eph. i. 7; chap. ii. 13, 14; Col. i. 20–22.
Hence, therefore, we must gather, that the blood of Christ is of infinite value, for that he offereth mercy to the biggest of sinners. Nay, further, since he offereth mercy in the first place to the biggest sinners, considering also, that this first act of his is that which the world will take notice of and expect it should be continued unto thee end. Also it is a disparagement to a man that seeks his own glory in what he undertakes, to do that for a sport, which he cannot continue and hold out in. This is our Lord’s own argument, “He began to build,” saith he, “but was not able to finish;” Luke xiv. 28.
