Our Disqualification of Sin Is Our Qualification for Grace...

"He came as a Physician for the sick, and does not expect that they should recover their health, in the least degree, before they come to Him (Matt. 9:12 ). The vilest sinners are fitly prepared and qualified for this design, which is, to show forth the exceeding riches of grace, pardoning our sins, and saving us freely (Eph. 2:5, 7). For this end the law of Moses entered that the offence might abound, that so, where sin abounded, grace might much more abound (Rom. 5:20). He loved us in our most loathsome sinful pollution, so as to die for us, and much more will He love us in it, so as to receive us when we come to Him for the purchased salvation. He has given full satisfaction to the justice of God for sinners, that they might have all righteousness and holiness, and all salvation only by fellowship with Him through faith. Therefore, it is no affront to Christ, or slighting and condemning the justice and holiness of God, to come to Christ while we are polluted sinners..."
