I invite you to read and meditate on these words from the late Martyn Lloyd-Jones, former pastor of Westminster Chapel in London, as he proclaimed the message of the cross of Christ. The following is an excerpt from a sermon he preached to his congregation in the fall of 1963. The series of sermons on Galatians 6:14 was published by Crossway Books as The Cross: God's Way of Salvation in 1986.
"It does not matter what you have been, men and brethren . . . I do not know you, my friends, not individually, most of you, but I know the most important thing about every single one of you, and that is that each of you is a vile sinner. I do not care who you are, because all have sinned and come short of the glory of God. I do not care what particular form your sin takes. There is a great deal of attention paid to that today. The preacher is not interested in that. I do not want a catalogue of your sins. I do not care what your sins are. They can be very respectable or they can be heinous, vile, foul, filthy. It does not matter, thank God. But what I have authority to tell you is this. Though you may be the vilest man or woman ever known, and though you may until this moment have lived your life in the gutters and the brothels of sin in every shape and form, I say this to you: be it known unto you that through this man, this Lord Jesus Christ, is preached unto you the forgiveness of sin. And by him all who believe, you included, are at this very moment justified entirely and completely from everything you have ever done - if you believe that this is the Lord Jesus Christ, the Son of God, and that he died there on the cross, for your sins and to bear your punishment. If you believe that, and thank him for it, and rely utterly only upon him and what he has done, I tell you, in the name of God, all your sins are blotted out completely, as if you had never sinned in your life, and his righteousness is put on you and God sees you perfect in his Son. That is the message of the cross, that is Christian preaching, that it is our Lord who saves us, by dying on the cross, and that nothing else can save us, but that that can save whosoever believeth in him." (Lloyd-Jones, p. 35-36 The Cross, 1986)
