Earlier today I tweeted this: “God comes to us in three books — nature, law, and gospel. Read plainly, we read God above us, God against us, and God with us.”
I have been asked for additional explanation, and so here it is. The responses ranged from huh? what? to “you sound like Michael Horton.” But this thought is actually a reworking of something I read from Matthew Henry, and shows how, once again, I am sitting on the edge of the fountain in the central square of Reformedville, just swinging my legs.
First, the Scripture: “And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross” (Col. 2:13-14).
There are differences between Lutherans and the Reformed on the three uses of the law (usus legis), but the differences are not over whether there are three uses.
There is a use of the law that convicts us of our need for Christ. If the basic message of the gospel is preached by evangelists whose message is “repent and believe,” this creates the obvious question — “repent of what?” That question cannot be answered without a standard, and the standard in Scripture is the law of God. This use of the law is essential in evangelism — more rich young rulers need to go away sad.
