Repent ye therefore… – Acts 3:19

The text says, “Repent ye therefore.” The apostle was logical: he had a reason for his exhortation. It was not mere declamation, but sound reasoning. “Repent ye therefore.” What, then, was the argument? Why, because you, like the Jews, have put Jesus Christ to death. This was literally true of the people to whom he spake: they had had a share in Christ’s execution. And this is spiritually true of you to whom I speak. Every sin in the essence of it is a killing of God. Do you comprehend me? Every time you do what God would not have you do, you do in effect, so far as you can, put God out of His throne, and disown the authority which belongs to His Godhead; you do in intent, so far as you can, kill God. That is the drift of sin-sin is a God-killing thing. Every violation of law is treason in its essence-it is rebellion against the lawgiver. When our Lord Jesus Christ was nailed to the tree by sinners, sin only did then literally and openly what all sin really does in a spiritual sense. Do you understand me? Those offendings of yours which you have thought so little of, have been really a stabbing at the Deity. Will you not repent, if it be so? While you thought your sins to be mere trifles, light things to be laughed at, you would not repent; but now I have shown you (and I think your conscience will bear me out) that every sin is really an attempt to thrust God out of the world, that every sin is saying, “Let there be no God.” Oh! then there is cause enough to repent of it. Come hither and reason with me, thou who hast broken God’s law…If you can really believe that though you did not nail Christ to the cross, nor plait the crown of thorns and put it on His head, nor stand and mock Him there, yet that every sin is a real crucifixion of Christ, and a mockery of Christ, and a slaughter of Christ. Then, truly, there is abundant reason why you should repent and turn from it. ~ C.H. Spurgeon
